search a directory on my site

I have about 300 word/pdf files that I want to create a search box to search just that directory and pull up all results on the same page. Could someone please help me with this.

Thanks
Derek McIntire

Might run a bit slow. Using a database with a precompiled list of words might be beneficial.

PHP Code:

---

<?php
function searchfiles($search,$dir) {
$results = array();
$n=0;
$opendir = opendir($dir);
while ($file = readdir($opendir)) {
if (in_array($file,array('.','..','otherfile.ext','....'))) continue;
//leave '.' and '..', and add any other files to skip... but try to keep mostly only searched files in this directory
if (!strpos($search,file_get_contents($dir.'/'.$file))) continue;
$array[$n] = $file;
$n++;
}
return $array;
}

print_r(searchfiles($search,'mydocs')); //set mydocs to your directory
//$search must be the text to match
?>

---

The formatting will be a bit off, and the files won't be links or anything, but you should be able to figure that out.

Thank You
I will try it and see

where would I put the search box and the submit button in this script?

You would want to do something like this:

Code:

---

<?php
function searchfiles($search,$dir) {
$results = array();
$n=0;
$opendir = opendir($dir);
while ($file = readdir($opendir)) {
if (in_array($file,array('.','..','otherfile.ext','....'))) continue;
//leave '.' and '..', and add any other files to skip... but try to keep mostly only searched files in this directory
if (!strpos($search,file_get_contents($dir.'/'.$file))) continue;
$array[$n] = $file;
$n++;
}
return $array;
}


if (isset($_POST['search'])) {

print_r(searchfiles($_POST['term'], 'mydocs')); //set mydocs to your directory
//$search must be the text to match
}

else {
?>
<form action="<?php echo $_SERVER['PHP_SELF'];?>" method="POST">
Search Term: <input type="text" name="term"> <input type="submit" name="search">
</form>
<?php
}
?>

Hope this helps.

I think I know the answer to this ? but If I have php anywhere in my page do I need to save that page with a .php extention

Yes, or at least set up the server to parse whatever file extension you name it to to serve as a PHP file. On most server installs though, you will want to name it as myfile.php (where myfile is the name of the file).

Hope this helps.

Thank You for your time

I did everything and I posted it and this what I am recieving on the page that it is susposed to display

Warning: file_get_contents(php): failed to open stream: No such file or directory in /home/content/d/e/r/derekm806/html/ordinances.php on line 69

This is what is on Line 69 of the php file.

if (!strpos($search,file_get_contents($ord.''.$ordinances.php))) continue;


Could you tell me what I am doing wrong.

DM

You took out the slash.

$dir.'/'.$file --> dir/file.ext

Ok Last post for this: sorry to be a such a moron but now I am getting this

Warning: strpos(): Empty delimiter. in /home/content/d/e/r/derekm806/html/ordinances.php on line 69

This is what is on Line 69 of the php file.

if (!strpos($search,file_get_contents($ord.'/'.$ord))) continue;


Could you tell me what I am doing wrong.

DM

Is the variable "$ord" defined elsewhere in the script? If not, that would be the reason why. I recommend using djr's script; and if needed, using my modification to it.

Hope this helps.

Well, to start, you're using the same variable twice.

So, that's like searching for directory/directory, or file.ext/file.ext, neither of which will end up giving you any results.

file_get_contents() returns the data in a file on your server. It uses a path to find the file. dir1/dir2/dir3/file.ext is an example of this.

Using $dir.'/'.$file SHOULD return directoryname/filename.extension, assuming $dir and $file are set correctly.

In the script I wrote, both of these are set. I'm not sure why you are changing the variable names. You're welcome to do so, but...
1. Changing the names can cause problems (and likely has) since you need to be completely consistent throughout the script so no references are lost.
2. Using generic names like I did (though unrelated to whether the script works or not, since variable names serve no purpose but identification) is helpful because you know what it is, within the function. Using "$dir" makes more sense than "$images", just as naming a variable "$number" makes more sense than "$one", etc. It's up to you, but I like having generic names within a function. In the rest of your script, do whatever you want (as long as it makes sense, since that's the most important part-- being able to follow what's going on).

At this point, I'd say decide why you are changing the variable names. You could try going back or you could be sure that all instances have changed.
You may want to paste the full source code here (skip all HTML as that won't be helpful).

EDIT: Sorry, testingsite. I was writing while you posted.

Thanks Both of you Give me a minute and I will redo it to what you originally had and post what I have so for here so you can see what I have

Thanks a bunch
DM

Ok here is what I have:

Quote:

<?php
function searchfiles($search,$dir) {
$results = array();
$n=0;
$opendir = opendir($dir);
while ($file = readdir($opendir)) {
if (in_array($file,array('.','..','otherfile.ext','....'))) continue;
//leave '.' and '..', and add any other files to skip... but try to keep mostly only searched files in this directory
if (!strpos($search,file_get_contents($dir.'/'.$file))) continue;
$array[$n] = $file;
$n++;
}
return $array;
}


if (isset($_POST['search']) )

print_r(searchfiles($_POST['term'], 'ord')); //set mydocs to your directory
//$search must be the text to match


else {
?>
<form action="<?php echo $_SERVER['PHP_SELF'];?> method="POST">
Search Term: <input type="text" name="term"> <input type="submit" name="search">
</form>
<?php
}
?>

---

When I post it I go to the form type in a key word to search and I am getting a page not found and the url is:

Quote:

---

http://www.mysite.org/mypage.php%20m...h=Submit+Query

---

This is what I have can you tell what is wrong

I am kind of getting this a little better so maybe with you guys help I wont have to bother ya much more.

Thanks
DM

Sorry about that, forgot to add a closing quote after the form action like so:

Code:

---

<form action="<?php echo $_SERVER['PHP_SELF'];?>" method="POST">

---

That should fix it

Ok That made it stop giving me the page not found and any errors so we are getting somewhere but no all that it is doing is when i type a word in it just refreshes the page basically and doesnt show any results.

here is what I have

Quote:

---

<?php
function searchfiles($search,$dir) {
$results = array();
$n=0;
$opendir = opendir($dir);
while ($file = readdir($opendir)) {
if (in_array($file,array('.','..','otherfile.ext','....'))) continue;
//leave '.' and '..', and add any other files to skip... but try to keep mostly only searched files in this directory
if (!strpos($search,file_get_contents($dir.'/'.$file))) continue;
$array[$n] = $file;
$n++;
}
return $array;
}


if (isset($_POST['search']) )

print_r(searchfiles($_POST['term'], 'ord')); //set mydocs to your directory
//$search must be the text to match


else {
?>
<form action="<?php echo $_SERVER['PHP_SELF'];?>" method="POST">
Search Term: <input type="text" name="term"> <input type="submit" name="search">
</form>
<?php
}
?>

---

Not sure if this will work or not, but you could try this:

Code:

---

<?php
function searchfiles($search,$dir) {
$results = array();
$n=0;
$opendir = opendir($dir);
while ($file = readdir($opendir)) {
if (in_array($file,array('.','..','otherfile.ext','....'))) continue;
//leave '.' and '..', and add any other files to skip... but try to keep mostly only searched files in this directory
if (!strpos($search,file_get_contents($dir.'/'.$file))) continue;
$results[$n] = $file;
$n++;
}
return $results;
}


if (isset($_POST['search'])) {

print_r(searchfiles($_POST['term'], 'ord')); //set mydocs to your directory
//$search must be the text to match
}

else {
?>
<form action="<?php echo $_SERVER['PHP_SELF'];?>" method="POST">
Search Term: <input type="text" name="term"> <input type="submit" name="search">
</form>
<?php
}
?>

---

Changes made are in red. Hope this helps.

<form action="<?php echo $_SERVER['PHP_SELF'];?> method="POST">
There's no close quote on the action.

I have no idea why it's generating such a string in the URL, but there's no real point in setting the action to that anyway. Using simply action="" will go to the same page.

I was under the impression that that was invalid, but could be wrong. Anyways, I fixed that in my few posts as well as pointed it out about the closing quote. As for the script refreshing to itself, not sure what would be causing that.

Ok I know you are probably getting tired of me so hopefully this post will solve it all.

I put the quotes in and now I am getting this

Quote:

---

Warning: strpos(): Empty delimiter. in /home/content/d/e/r/derekm806/html/ordinances.php on line 69

---

And Line 69 is this:

Quote:

---

if (!strpos($search,file_get_contents($dir.'/'.$file))) continue;

---

And just for further refreshing here is the whole code again:

Quote:

---

<?php
function searchfiles($search,$dir) {
$results = array();
$n=0;
$opendir = opendir($dir);
while ($file = readdir($opendir)) {
if (in_array($file,array('.','..','otherfile.ext','....'))) continue;
//leave '.' and '..', and add any other files to skip... but try to keep mostly only searched files in this directory
if (!strpos($search,file_get_contents($dir.'/'.$file))) continue;
$array[$n] = $file;
$n++;
}
return $array;
}


if (isset($_POST['search']) )

print_r(searchfiles($_POST['term'], 'ord')); //set mydocs to your directory
//$search must be the text to match


else {
?>
<form action="" method="POST">
Search Term: <input type="text" name="term"> <input type="submit" name="search">
</form>
<?php
}
?>

---

And you said earlier that something about assuming $dir and $file are set correctly, where was i susposed to set that at :)

Thanks
DM

It would be on this line:

Code:

---

print_r(searchfiles($_POST['term'], 'ord')); //set mydocs to your directory

---

The part in red is the directory, the file is found in that directory and "automatically" defined; if that makes sense.

so your saying I have it right?

If the directory you are searching in is called "ord", then yes. If not, then you need to change it to the directory you wish to search through.

well that is the exact directory and it is not working for some reason...

what does "Empty delimiter" mean?

With this php code

function searchfiles($search,$dir) {
$results = array();

$opendir = opendir($dir);

//leave '.' and '..', and add any other files to skip... but try to keep mostly only searched files in this directory
if (!strpos($search,file_get_contents($dir.'/'.$file))) continue;
$array[$n] = $file;
$n++;
}
return $array;
}


if (isset($_POST['search']) )

print_r(searchfiles($_POST['term'], 'ord')); //set mydocs to your directory

else {
?>
<form action="" method="POST">
Search Term: <input type="text" name="term"> <input type="submit" name="search">
</form>
<?php
}
?>

I am getting no form at all and getting this on my page..

Any ideas.....

I'm not sure if action="" is invalid. If so, just use the name of your page. It's possible to generate this with PHP, but it was giving you errors before, so I don't see the point.

As for the strpos() error, I'm assuming that either $search or file_get_contents() is blank. You can suppress the error using:
if (!@strpos($search,file_get_contents($dir.'/'.$file))) continue;

But I'm not sure if that will help, if something is going wrong.

You're not getting any results at all?

Ok Here is the web site address. Maybe if you see what it is doing you will be able to tell more about it

www.bayarkansas.org/ordinances.php

Thanks
DM

Nothing returns results. I assume you have 3 files being searched right now?


The code above should work, if the system is setup correctly (sending the form, etc). However, try changing this:
if (isset($_POST['search']) )
to:
if (isset($_POST['term']))

See if that helps.

Actually there is a couple hundred files in that directory. But there may only be a few with the term I am searching

Any Suggestions or am I totally screwed
DM

Could any of the files have no content?

If so, that could be the reason you are getting the empty message.

Make this line: if (!strpos($search,file_get_contents($dir.'/'.$file))) continue;
This:
$fc = file_get_contents($dir.'/'.$file)
if ($fc == '') continue;
if (!strpos($search,$fc)) continue;

Ok I did what you said but now the page will not load and all that i see is a this

Just so I know we are on the same page the only thing I needed to change in the code below is the dir in print_r(searchfiles($_POST['term'], 'ord')); //set mydocs to your directory

Quote:

function searchfiles($search,$dir) {

</form>
<?php
}
?>

You should use the new lines of code that I added, to error correct if a file IS empty. However, there was a typo. I forgot a semicolon at the end of a line.
$fc = file_get_contents($dir.'/'.$file);

Quote:

---

$fc = file_get_contents($dir.'/'.$file)
if ($fc == '') continue;
if (!strpos($search,$fc)) continue;

---

Does the above code need to be exactly like it looks or on one line

That's right. But again, it's missing a semi colon. Add that to the first line, like in my last post.

after doing the above i am not getting no warning now;

Now I am getting a refreshed page with no form to fill out?
What next:):):):)
????????
I know I am probably getting on your nerves sorry
DM

djr33, you're missing one key point.
