HTML Checkbox Post to PHP

[petenetman]

I am trying to post a checkbox value form HTML to PHP thus

HTML

<form>

<input type="checkbox" name="IA" value="IA" /> IA Only<br />

</form

 

PHP

$_POST['IA'];

if($_POST['IA'] !=TRUE){

echo "IA Only Selected"

}

If I run the page with the above PHP I get an Error 500 - What am I doing wrong?

 

Thanks in advance

not sure for what reason your getting a 500 error. I might just point out that checkboxes pass as "on" or "off" from my experience so that script shouldn't actually display anything (i could be wrong though).

Hi,

It seems that I can't echo the value of the checkbox in from Html to display in PHP.

 

Can anyone show me some basic code so I can figure it out please?

[Tazerenix]

hmm, in your html you've said Value = 'IA', that might be the problem. Here is some code you can try:

 

<form action="phppage.php" method="post">
<input type="checkbox" name="IA" /><br />
<input type="submit" value="Submit" />
</form>

phppage.php:

<?php
if ($_POST['IA'] == "on")
echo "checkbox checked";
else
echo "checkbox unchecked";
?>

That should work.

Thanks Tazerenix

 

I solved it with radio buttons and that seems to work and looks just as good.

 

Can't understand why the checkboxes don't work but thanks for the code.

 

Take it easy!
