Hi,

I need to compare a php variable to a checkbox value and if they match turn that checkbox to TRUE. The checkbox values are not submitted from a form they reside on the same page as the PHP code. I'm not sure how to get the checkbox value into a PHP variable for comparison and if a match is found set the checkbox to TRUE.

Thanks

Don

relevant code:-

<?
//get nights from table.
$lNights = $lobjVenueEdit->get("fldVenueNights");

//seperate string into individual nights
$lNights = explode(",",$lNights);

foreach($lNights AS $lNight){
$lNight = trim($lNight);
//some code here which will compare $lNight
//with the checkbox values
}
?>

Sunday

Monday

Tuesday

Well, to make a checkbox checked, you need to have the word 'checked' in the tag. For example, something like this:

<input type="checkbox" name="cbxSunday" value = "Sunday" <strong>checked </strong>/>'

...so what you could do it set a bunch of empty variables or an array and set those values to 'checked' as needed. For example:

<?php
if (condition)
{
$checked['cbxSunday'] = 'checked';
}
else
{
$checked['cbxSunday'] = '';
}
?>

<input type="checkbox" name="cbxSunday" value = "Sunday" <strong><?php echo $checked['cbxSunday'] ?></strong>/>
