Question

I am populating a list of checkboxes from a foreach loop, and giving each an ID. I have added a set of divs below that would appear, depending on which checkbox is created. I was thinking I could load the id variable into a jQuery if statement, and then use a .toggle to show or hide the corresponding div.

<?php 
//Call Programs
$getPrograms = Doctrine::getTable('Program')->createQuery()->where('subsection=?', 'mfa')->orWhere('subsection=?', 'mps')->orWhere('subsection=?', 'mat')->orWhere('subsection=?', 'ma')->orderBy('title ASC')->execute(); ?>

    <div class="form_row">
     <label>
    <span><sup class="required_form_item">*</sup>Select Program</span>
    </label>
        <div class="buttonColumn" style="margin-left:170px;">
        //loop the records in with checkboxes
        <?php foreach ($getPrograms as $prog): ?>
              <?php 
              $subsection = $prog->getSubsection();
              $subsection = strtoupper($subsection);

              $trimProg = trim($prog->getTitle(), ' ');
              $removeChars = array(" ", "&");
              $trimProg = str_replace( $removeChars, '', $trimProg ); 
              $trimProg = preg_replace('/\s\s+/', '_', $trimProg);

              ?>
              //custin id matches record title
              <input type="checkbox" name="program" class="isChecked" id="<?php echo $trimProg; ?>" value="<?php echo $subsection . " " . $prog->getTitle() ?>" /><?php echo $subsection . " " . $prog->getTitle() ?><br />
        <?php endforeach ?>
        </div>
    </div> 

The following divs would be set to display:none until the matching checkbox is checked.

    <div class="form_row sessionTime" id="Program1" style="display:none;">
    Please choose an session time:
    <input type="checkbox" name="schedule" value="5:00 pm" />5:00 pm<br />
    </div>

    <div class="form_row sessionTime" id="program2" style="display:none;">
    Please choose an session time:
    <input type="checkbox" name="schedule" value="10:00 pm" />10:00 pm<br />
     </div>    
    ...

And this is what I thought would work…but alas…it doesn’t

$('.isChecked').click( function() {

    if ( $(this).is(':checked') ) {
      $thisID = $(this).attr("id");
      $('.'+ $thisID).show();
    }
    else {
      $('.'+ $thisID).hide();
    }
  }
); 

Answer 1

You should be using “Program1” as class name instead of id like this

<div class="form_row sessionTime Program1" style="display:none;">
  Please choose an session time:
  <input type="checkbox" name="schedule" value="5:00 pm" />5:00 pm<br />
</div>

And your jQuery code should work, which you can simplify as follows:

$('.isChecked').click( function() {
  if ( $(this).is(':checked') ) {
    $('.'+ this.id).show();
  }
  else {
    $('.'+ this.id).hide();
  }
});
