Custom field values repeating

5 Views

I’m at a loss. I’ve got a custom meta box with the ‘multicheck’ code that Jan created. It’s working great. My issue now is getting the data to return properly.

Scenario: there are 5 possible values, each with the same meta_key. What I am trying to do is display specific content if a value is stored with one of the 5 possible values. What is happening is that the content is repeating.

Current code: 

    <?php
    global $post;
$offerings = get_post_meta($post->ID, "evol_offerings_select", false);
if ($offerings[0]=="") { ?>

<!-- If there are no custom fields, show nothing -->

<?php } else { ?>

<div class="offerings">
    <h3>offerings:</h3>
            <?php 
            foreach ($offerings as $offering) {
                if ($offering["hot"]==true) {

  1. Your foreach is the problem. You’re iterating once for each offering, yet you’re evaluating ALL offering values in the array each time. So your PHP is dutifully printing all available offerings * the number of offerings. I’d say go without the foreach() and see what happens.

    EDIT 1
    Also please note, you’re casting strings to arrays. You’re trying to look up values in an array based on an invalid key. $offerings[“hot”] – $offerings[“kids”] don’t exist, as far as PHP is concerned. $offerings[0] – $offerings[4] DO exist.

    EDIT 2
    Okay, you want the following in place of your foreach():

    if(in_array("hot", $offerings)){
// print hot results
}

if(in_array("chill", $offerings)){
//print chill results
}

    etc.

    EDIT 3

    Or, if I think about it further, you could stick with the foreach() in the following manner:

    foreach($offerings as $offering){
 switch($offering){
   case "hot":
    //print hot stuff
   break;
   case "chill":
    //print chill stuff
   break;
 }
}

    EDIT 4

    If you were dealing with a larger data set, I would probably go with the switch() version, as the in_array() calls scan the whole array each time, which could get expensive, while the foreach() will simply iterate through the array and move the array pointer with each iteration. Your call, but I’m thinking that would be the way to go in order to future-proof and performance-proof. (The performance hit on a 5 value array for in_array() is likely minuscule, but these things add up.)

  2. PHP will evaluate

    $offering["someKey"]==true

    as true for a key so long as the value for that key is not empty, so I suspect get_post_meta() is returning something (“null” or even ” “) for those values.

    try using 

    $offering["someKey"]===true

    for strict equality and it should work.

  3. Can you share the code that you are using to register those boxes? Sounds like each time you are saving, each value is overwriting each other. You will need to save the values into an array.

  4. Try this:

     <?php
    global $post;
    $offerings = get_post_meta($post->ID, "evol_offerings_select", false);
    $offeringDefinitions = array(
        'hot'   =>(object)array('name'=>'Hot 90',       'temp'=>'105',      'time'=>'90'),
        'flow'  =>(object)array('name'=>'Flow 75',      'temp'=>'80',       'time'=>'75'),
        'warm'  =>(object)array('name'=>'Warm 60',      'temp'=>'90',       'time'=>'60'),
        'chill' =>(object)array('name'=>'Chill 30',     'temp'=>'75-80',    'time'=>'30'),
        'kids'  =>(object)array('name'=>'Kids Class',   'temp'=>'comfy',    'time'=>'60')
    );
    $offeringsInUse = array();
    forEach($offerings as $offering) {
        forEach($offeringDefinitions as $offeringName=>$offeringDefinition) {
            if ($offering[$offeringName]) $offeringsInUse[$offeringName]=$offeringDefinition;
        }
    }
?>
<?php if (count($offeringsInUse)>0): ?>
    <div class="offerings">
        <h3>offerings:</h3>
        <?php forEach ($offeringsInUse as $offering): ?>
            <div class="single_offering">
                <h3><?php echo $offering->name ?></h3>
                <p class="class_info">temp: <?php echo $offering->temp ?>&deg;&nbsp;&nbsp;&nbsp;time: <?php echo $offering->time ?>min</p>
            </div>
        <?php endForEach ?>
    </div>
<?php endIf ?>

    What I’ve done here is:

    1. Preset the defintions of the offering types. Ideally this would be data driven, but since it’s obviously not, this is the best alternative.
    2. Check the definitions against the various offerings available per… offering*, and stack that into an array.
    3. If that array isn’t empty, display the appropriate chunk of HTML, filling in the offering attributes as you iterate over the array.

    *Actually, that’s what I’ve gleaned from your suggested requirements – that a given program has a set of offered activities, and that these activities need to be enumerated… or something. Maybe you could be more clear.
