Removing extra and
with preg_replace

qwikad.com — Thu, 23 May 2013 19:28:32 GMT

Hi there!

Sometimes people post ads with html tables in them and more often than not they have extra tags and

which interferes with my site's layout.

Is it possible to strip all EXTRA and

with preg_replace?

Thank you for any input.

Directory hyperlinks

phrozen1 — Wed, 22 May 2013 16:16:52 GMT

Can anyone help me out with this?

I have a website where I post results from races in .html or .pdf.

Every time I post the results in a directory, I have to manually create a hyperlink

I want a php script that will scan the directory and then create a list of hyperlinks ordered by the date of the file. I also would also like the links to not have the .pdf or .html extension on the end. I also do not want the underscore in the hyperlink but a space instead.

Thanks for any help

Php contactform handler with issues

seccondbest — Wed, 22 May 2013 13:34:59 GMT

I have been looking at several pages of sollutions but I am lost in the woods.

Obviously i am using a contactform on my website, I have found a working script written by Betty, and I have contacted this person for some support however that was 5 days ago and no answer yet.

the Html part of the contact form asks for:

name,
surname,
email address,
message,
phonenumber,

If any of these required fields are not or not correctly filled in the PHP script opens up a white pages filled with error messages.
Than the user has to arrow back to the form page and start from scratch, this is ot only anoying but painfull, if you just typed a message of 1000 words and you typed your phone number wrong you get to do it all again lol

further more there is no thank you except after submitting where it clears the form reloads the page and in the addressbar it states the name of the page/thankyou

I have tried to tweak a few things and messed it up badly, i ended up spamming my own e-mail with over 50 test messages I need help!

Since I can not upload the php script I have copied and past it here,

What I would like to have:

error messages in a windows popup without clearing the entire form
a thank you message in a windows popup and clear the form/reload the page

***** original php script ****

PHP Code:



    #**********************************************
    # Contact Formulier vanBetty

if(isset($_POST['email'])) {
    
    // Pas deze twee regels aan.

When should error suppression be used?

james438 — Thu, 16 May 2013 05:21:09 GMT

When incorporating code from other sources I sometimes see it utilizing error suppression (@). For debugging purposes I turn it off and often find it unnecessary. I think that it is nice to have options with php like error suppression, but I can't figure out when it would be useful. Where/when should it be best used?

Accessing a variable in a function from the main script

keyboard1333 — Wed, 15 May 2013 10:12:10 GMT

G'day all!

Say I've got this function that connects to the mysql database -

PHP Code:


function sqli_connect($username, $password) {

        $connection = mysqli_connect("localhost", $username, $password);

        //Test connection to database

        if(mysqli_connect_errno()) {

            echo "Installation error: Could not connect to database.";

            exit;

        }

    }

Then I call it from here -

Code:


sqli_connect('****', '****');

//Create the databases

if(mysqli_query($connection,"CREATE DATABASE my_db")) { //Executes mysqli query and tests for a return of true at the same time

        echo "Database my_db created successfully";

} else {

        echo "Error creating database: " . mysqli_error($con);

}

?>

How can I give it the connection variable from the function?
Thanks all :)
