[SOLVED] PHP and Checkboxes

[limitphp]

I have a checkbox in a form.  How do I determine if its checked or not with php?

 

The $_POST['checkboxname']; seems to get all values, except for the checkbox.

[Flames]

because you have multiple check boxes with the same id and if its ticket then $_POST['checkbox'] should have those values, not to sure how to seperate the values though?

[laffin]

CheckBoxes either return the value or dun

so ya can use isset to determine the value

 

$checkbox = isset($_GET['mycheckbox'])?1:0;

 

1 if it was checked

0 if it wasnt

if the checkboxes all have different names, then $_POST['checkboxname'] should be set to the value or to 'on' if no value was used. if you want to use the same name, you should use it like so:

<input type="checkbox" name="chkbox[]" value="val1" />
<input type="checkbox" name="chkbox[]" value="val2" />
<input type="checkbox" name="chkbox[]" value="val3" />

and in PHP, $_POST['chkbox'] should be an array of which values you selected

Only checked checkboxes are returned to PHP.

 

Please post the source for your form and the script that's processing it.

Ok, I'm sorry, let me clear this up...I miswrote ....I use $_POST to get all form items successfully.  My inputtexts.  I only have one checkbox (if you used multiple...wouldn't you use radio buttons instead?).

The $_POST on the checkbox doesn't seem to get any value.

I put in your code and now all it returns is a 0, even when its checked.

[limitphp]

$rememberMe = isset($_POST['remember'])?1:0;
.
.
.
<SCRIPT>
alert('<?php echo $rememberMe ?>');
</script>
.
.
.
<FORM NAME="frmLogin" METHOD="post" ACTION="index.php">
<INPUT TYPE="checkbox" NAME="remember">
</FORM>

All I'm seeing now on the alert box is a 0.

 

 

[limitphp]

Nevermind, I'm sorry.  I was closing the FORM before the checkbox.

 

<?php if ($loginExist==0){ ?>
				<FORM NAME="frmLogin" METHOD="post" ACTION="index.php">					
				Username<INPUT TYPE="TEXT" NAME="username" SIZE="15"> 
				Password<INPUT TYPE="password" NAME="password" SIZE="15">
				<INPUT TYPE="hidden" NAME="mode" VALUE="1">
				<INPUT TYPE="submit" VALUE="Login">
				</FORM>
			<?php }else{ ?>					
					<?php echo $fname ?><br>						
			<?php } ?>
				Register | Our Mission
			<?php if ($loginExist==0){ ?>
				    <INPUT TYPE="checkbox" NAME="remember">Remember Me

			<?php } ?>

 

I fixed it and now it works.

 

<?php if ($loginExist==0){ ?>
				<FORM NAME="frmLogin" METHOD="post" ACTION="index.php">					
				Username<INPUT TYPE="TEXT" NAME="username" SIZE="15"> 
				Password<INPUT TYPE="password" NAME="password" SIZE="15">
				<INPUT TYPE="hidden" NAME="mode" VALUE="1">
				<INPUT TYPE="submit" VALUE="Login">

			<?php }else{ ?>					
					<?php echo $fname ?><br>						
			<?php } ?>
				Register | Our Mission
			<?php if ($loginExist==0){ ?>
				    <INPUT TYPE="checkbox" NAME="remember">Remember Me
</FORM>

			<?php } ?>

 

I guess thats why you say post your source code....

I just didn't want to post all of it because its a pretty big page.

Thank you guys...and sorry for the misinformation on my part.
