control in mailform

**chechu** · 07-21-2008, 12:47 PM

I can still send without filling in all fields.

**GarethMc** · 07-21-2008, 01:10 PM

Problem now is a simple typo ... you do need to check that all the values you check for are correctly spelt.... If you look at the HMTL that defines the email text box:

HTML Code:

<input type="text" name="email" value=" your email adress"

and then the check in the if in PHP

PHP Code:


&& $_POST['email'] != " your e-mail adress" && strlen(trim($_POST['email']))> 0 {

Notice the spelling mistake now? Its up to you to choose which one of the two to correct to fix the error....

**chechu** · 07-21-2008, 01:22 PM

Code:

<?php 


if ($_POST["action"] == "send"){ 

$error = false; 

if ($_POST['name'] != " your name" && strlen(trim($_POST['name'])) > 0 
&& $_POST['email'] != " your email adress" && strlen(trim($_POST['email']))> 0 
&& strlen(trim($_POST['message'])) > 0) {  
mail ("info@site.com", "via website",  
" 
Name: ".$_POST['name']." 
E-mail: ".$_POST['email']." 
Message: ".$_POST['message']." 
", 
"From: ".$_POST['name']." <".$_POST['email'].">"); 
$subject = "your message";  
$msg = " 
This is an automatically sent email. Please do not reply. 
Dear $_POST[name], 
Thanks for your message to Ceci. 
She will get back to you as soon as possible. 
This was your message:

mail($_POST[email], $subject, $msg);  
echo ''; 
} 
else{ 
$error = true; 
} 
} 

?> 

<html>

Somzetimes it works, sometimes it doesn't. Weird.
Also, the website construction has changed. Should I replace the whole html code where I made it red ?

**GarethMc** · 07-21-2008, 01:25 PM

Yes you should and you should also add the closing tags at the end (i.e. </body> and </html>)

I was just a bit lazy using proper XHTML tags such as the doctype decleration and such.. just add the rest of your HTML in where it goes and all should be fine...

As for working sometimes .. remember that to the if statement "your email adress" and " your email adress" (see the space after the opening quote) are not the same...

Where do you see the difference ? Can you color it, please ?

Also, is it possible, instead of having a text when a field is not filled in, that the border of the input field turns red ?

I was just pointing out that string based comparisons are not incredibly reliable. Someone could just take the space out from in front of " your email adress" in the text box and click submit and it will work, because the if is checking for that text with a space...

Adding a check to see if the submitted text is in a valid email address format would be handy and isn't necessarily hard to do either using regex or just the PHP string functions...

Try things out for yourself. Play with the code. Half the battle of learning to program is fixing bugs.. it helps remind you in future what could be causing your problems so you don't repeat them.

So if I remove the space, it will always work !

Totally agree, but I know nothing of php, and trust me, have tried to, but I keep mixing/messing things up.

I have this:

Code:

<style type="text/css">
<!--
div#container {
    margin:0 auto;
    background: #f2f4f7;
}
label {
    float: left;
    width: 140px;
    text-align: left;
    padding-top: 5px;
}
input, textarea {
    padding: 3px;
    margin: 3px;
    border: 1px solid #bac5d6;
    font: 10px Verdana, sans-serif;
    background: #fff;
}
input.fout, textarea.fout {
    border: 1px solid #FF0000;
}
label.fout {
    color: #FF0000;
}
-->
</style>

Yes you can just alter the input tag based on the value of $error:

PHP Code:


<?php

if ($error)

{

?>

<input class="fout" type="text".........

<?php

}

else

{

?>

<input type="text" ........

<?php

}

?>
