If Statement Help

[wompninja]

Hi all,
I'm trying to figure out what syntax I need to use to make an if statement work with some code I am working with.

Basically I have some custom fields in wordpress pulling into this code but I need the table to only show the parts that have content. Here's the code I have so far and it pull the content in but I need to get an if statement working so that posts that don't have the content don't show the table structure.

<?php $ScheduleGroup = get_group('schedule'); // use the Custom Group name
  foreach($ScheduleGroup as $event){ ?>

<?php $semester=get($event['schedule_semester'][1]); ?>
    <?php if ( $semester ) : ?>
    <h3><?php echo $semester; ?> Schedule</h3> 
<table width="500" border="0" cellpadding="8" cellspacing="8">
  <tr >
    <td width="111" class="tabletitle">Campus</td>
    <td width="105" class="tabletitle">Completion Time</td>
    <td width="105" class="tabletitle">Days</td>
    <td width="105" class="tabletitle">Time</td>
  </tr>

  <tr>
    <td class="tableinfo"><?php echo $event['campusone'][1]; ?></td>
    <td class="tablewhite"><?php echo get('schedule_campus_1_completion_time', true); ?></td>
    <td class="tablewhite"><?php echo get('schedule_campus_1_days', true); ?></td>
    <td class="tablewhite"><?php echo get('schedule_campus_1_time', true); ?></td>
  </tr>  

</table>
    <?php else : ?>
    <?php endif; ?>
<?php } ?>

The Groups are duplicatable so that's why the code creates a number . Basically I just need this to work but my syntax is wrong.

<?php $semester=get($event['schedule_semester'][1]); ?>
    <?php if ( $semester ) : ?>
    <h3><?php echo $semester; ?> Schedule</h3> 
    <?php else : ?>
    <?php endif; ?>

Try this:

<? 
$semester=get($event['schedule_semester'][1]);
if(!empty($semester)): 
?>
<h3><?= $semester; ?> Schedule</h3>
<? 
else:
endif; 
?> 

I also simplified some of your code, sorry if your server does not support that.

That didn't work, I didn't get an error but the content didn't show up. For some reason I don't think the get($event['schedule_semester'][1]); works. I've cleaned up the duplicateable section and it all works showing the content. I just need to get an if statement working in correlation with it. Each $ScheduleGroup as $event shows a table with the class info in it. I need it to say if there is content in schedule_semester then show this table. Thanks for your help.

This worked, it was just backwards.

<?
$semester=get($event['schedule_semester'][1]);
if(!empty($semester)):
?>
<h3><?= $semester; ?> Schedule</h3>
<?
else:
endif;
?> 

Here's what I finally got to work.

<?php $myEvent = get_group('Schedule'); // use the Custom Group name
  foreach($myEvent as $event){ ?>

<?
$semester=get($event['schedule_semester'][1]);
if(!empty($semester)):
?>

<?
else:
?>

I was hasty in clicking the resolved button...

This is where I'm at. Instead of showing nothing if the argument is empty I get this error. Any ideas?

Anybody?

[bradgrafelman]

Sounds like $myEvent isn't an array. Have you tried using something like [man]var_dump/man to figure out what it is instead?

[wompninja]

I'm pretty new to php so I don't really know how to do what you're saying.

[bradgrafelman]

That's why I linked you to the manual page for [man]var_dump/man. Refer to it to learn how that function is called and what it does. Then, copy its output and paste it here for us to see.

[wompninja]

Thanks, I didn't notice it was a link.

I put this in

<?php $myEvent = get_group('Schedule'); // use the Custom Group name
  foreach($myEvent as $event){ ?>

<?
$semester=get($event['schedule_semester'][1]);
var_dump($semester);
?>

<h3><?php echo $event['schedule_semester'][1]; ?> Schedule</h3>

and I got this

bool(false)

but it still dumps out the correct schedule semester content in the h3

[wompninja]

You can see the result here.

[wompninja]

Ok, so I put the var dump on the wrong string... I put it on myEvent and I get this

array(2) { [1]=> array(13) { ["schedule_semester"]=> array(1) { [1]=> string(23) "EMT Basic Fall / Spring" } ["campusone"]=> array(1) { [1]=> string(12) "Spanish Fork" } ["schedule_campus_1_completion_time"]=> array(1) { [1]=> string(24) "2 Months (45 Class Days)" } ["schedule_campus_1_days"]=> array(1) { [1]=> string(16) "Nebo A or B Days" } ["schedule_campus_1_time"]=> array(1) { [1]=> string(15) "7:30 - 10:30 AM" } ["campustwo"]=> array(1) { [1]=> string(4) "Orem" } ["schedule_campus_2_completion_time"]=> array(1) { [1]=> string(10) "4-5 Months" } ["schedule_campus_2_days"]=> array(1) { [1]=> string(18) "Alpine A or B Days" } ["schedule_campus_2_time"]=> array(1) { [1]=> string(18) "11:45 AM - 2:45 PM" } ["campusthree"]=> array(1) { [1]=> string(18) "Thanksgiving Point" } ["schedule_campus_3_completion_time"]=> array(1) { [1]=> string(26) "4-5 Months (45 Class Days)" } ["schedule_campus_3_days"]=> array(1) { [1]=> string(18) "Apline A or B Days" } ["schedule_campus_3_time"]=> array(1) { [1]=> string(37) "7:30 - 10:30 AM or 11:30 AM - 2:30 PM" } } [2]=> array(7) { ["schedule_semester"]=> array(1) { [1]=> string(21) "EMT Basic 2011 Summer" } ["campusone"]=> array(1) { [1]=> string(18) "Thanksgiving Point" } ["schedule_campus_1_completion_time"]=> array(1) { [1]=> string(18) "2 Months (45 Days)" } ["schedule_campus_1_days"]=> array(1) { [1]=> string(9) "Mon - Fri" } ["schedule_campus_1_time"]=> array(1) { [1]=> string(15) "7:30 - 10:30 AM" } ["adate"]=> array(1) { [1]=> string(48) "Summer Session 2011: June 6, 2011 - Aug 10, 2011" } ["hsdate"]=> array(1) { [1]=> string(48) "Summer Session 2011: June 6, 2011 - Aug 10, 2011" } } }
