How to display Custom Meta Field Key and Value when using array

What would syntax look like when aiming to echo $variable with array containing multiple $var# = get_post_meta( get_the_ID(), ‘var#’, true). Currently I am able to echo array $var#, however after much research and testing if get_post_custom_keys(), get_post_meta(), and other similar functions I am confused about how to display $var# key.

Below is code snippet of what is currently producing partially intended results.
```
if ( have_posts() ) :

while ( have_posts() ) :
	the_post();
	$special_category_slug = get_post_special_category_slug();

$cpmf = array(    
        $var1 = get_post_meta( get_the_ID(), 'var1', true),
        $var2 = get_post_meta( get_the_ID(), 'var2', true),
        );

   if( ! empty( $cpmf ) ) {
    		echo '<h3>VAR1:</h3>' . $var1;
    		echo '<h3>VAR2:</h3>' . $var2;
      }
```
echo is accurately displaying $var# custom meta field value, how can the custom meta field key be displayed only when there is a value associated with key?

Based on the code you provided, the $cpmf array makes no sense, and this would accomplish what you want:
```
	$var1 = get_post_meta(get_the_ID(), 'var1', true),
	$var2 = get_post_meta(get_the_ID(), 'var2', true),

	if( !empty($var1) ) {
		echo "<h3>VAR1:</h3>$var1";
	}
	if( !empty($var2) ) {
		echo "<h3>VAR2:</h3>$var2";
	}
```
If the $cpmf array is needed in code you did not provide, then adjust the above accordingly.

Hi @diondesigns,

Your response works, how can this be achieved without multiple if statements (ex. $var1, $var2, etc.)? bc there will be an increasing amount of custom variables with custom meta field values.

In original code snippet, $var_name is displayed even if $var_value is empty… how to display $var_name, only if $var_value has data retrievable, otherwise both fields should not be displayed?
```
$cpmf = array(    
        $var1_name = get_post_meta( get_the_ID(), 'var1_value', true),
        $var2_name = get_post_meta( get_the_ID(), 'var2_value', true),
        );
```
Clarification
I thought code snippet of $cpmf array is declaration of $var1 (custom meta field name) and $var1(custom meta field value) was pulling $var1 value via get_post_meta(….var1, true) within while loop. I’ve adjusted the code snippet in an effort to distinguish name and value.

$var1_name has $var1_value, which is input data from wp custom meta value fields.

How do I achieve custom meta ‘name’ field display only when custom meta ‘value’ field has data entered/ available for display, otherwise ‘name’ and ‘value’ should not be displayed if either are empty?

Edit Below
Edit
```
$cpmf = array(    
                "testKey1" => get_post_meta( get_the_ID(), 'testValue1', true),
                "$testKey2" => get_post_meta( get_the_ID(), 'testValue2', true),
                $testKey3 => get_post_meta( get_the_ID(), 'testValue3', true),
            } 

foreach( $cpmf as $cpmfKey => $cpmfValue ){
                echo "$cpmfKey = $cpmfValue<br>";
```
Results from testing:
“testkey1” displays literal and get_post_meta, however custom meta name field is not dynamically generated.

if I try to call “$testKey2” as typed in custom meta name field input with $variable declaration, only get_post_meta() displays field value and not name (aka $testKey2).

And if I try to call $testKey3, neither name or value of custom meta field is displayed, which I presume is because no quotes. Sorry for the long verbose description of my “troubleshooting”. How do I dynamically generate the custom meta “name” field?

You’re on the right track. The following should do what you want:
```
	$cpmf = array(
		'var1' => get_post_meta(get_the_ID(), 'var1', true),
		'var2' => get_post_meta(get_the_ID(), 'var2', true),
	);

	foreach($cpmf as $key => $val) {
		${$key} = $val;
		if( !empty($val) ) {
			echo "<h3>{$key}:</h3>$val";
		}
	}
```
The ${$key} = $val; line will create variables $var1 and $var2.

The above can be further condensed because the $post variable is created by the “loop”. The code below is much perferred because it avoids calling get_post_meta(), which saves a potentially large number of DB queries.
```
	$cpmf = array('var1', 'var2');

	foreach($cpmf as $key) {
		${$key} = $val = $post->$key;
		if( !empty($val) ) {
			echo "<h3>{$key}:</h3>$val";
		}
	}
```

Hi @diondesigns,

${key} = $val; code that created variables from $var# worked exceptionally well. Thank you for bestowing your wisdom and patience upon me. This may seem a really simple question in lieu of above achievement.

How do I encapsulate every and all instances of key/value pairs within the foreach loop? I’ve isolated each single instance within html tags, however am having some glitches on how to enclose all key/value pairs within $cpmf loop.

What am I missing?
```
foreach( $cpmf as $cpmfKey => $cpmfValue ){
  ${$cpmfKey} = $cpmfValue;
    if( ! empty( $cpmfValue) ) {
      echo "<div class='cpmf'><h3>{$cpmfKey}:</h3>$cpmfValue</div>";
      }
    }
```
Other attempts to apply html tags to enclose all of $cpmf include ul/ li, div(with inline-block), and for giggles tried to enclose the foreach loop with html tag, which gave an error.

I am aiming to enclose and control this foreach loop as a block element, how would this be achievable, given above loop?

I think the following code within the foreach() loop would do what you want. Adjust it as required.
```
${$cpmfKey} = $cpmfValue;
echo '<div class="cpmf">';
if( !empty($cpmfValue) ) {
	echo "<h3>{$cpmfKey}:</h3>$cpmfValue<br />";
}
else {
	echo "<h3>{$cpmfKey}:</h3>(No Value)<br />";
}
echo '</div>';
```

Hey @diondesigns,

Code snippet above does enclose each key/value pair within the foreach loop in html tags, however it populates wrappers for key/value pairs that have no data available (which we resolved earlier in this thread).

I was able to achieve what you suggested as detailed in below snippet:
```
foreach( $cpmf as $cpmfKey => $cpmfValue ){
  ${$cpmfKey} = $cpmfValue;
    if( ! empty( $cpmfValue) ) {
      echo "<div class='cpmf'><h3>{$cpmfKey}:</h3>$cpmfValue</div>";
    }
  }
```
How do I achieve below with ‘cpmfWrapper’, so that it encloses all iterations of foreach loop with one wrapper, excluding key/value pairs that have no data available to display, given the if( !empty ($cpmf) ) statement?

How do I achieve this => <div class=”cpmfWrapper”> encloses all <div class=”cpmf”> :
```
<div class="cpmfWrapper">
 <div class='cpmf'><h3>cpmfKey1:</h3>cpmfValue1<br /></div>
 <div class='cpmf'><h3>cpmfKey2:</h3>cpmfValue2<br /></div>
 <div class='cpmf'><h3>cpmfKey3:</h3>cpmfValue3<br /></div> 
 <div class='cpmf'><h3>cpmfKey4:</h3>cpmfValue4<br /></div> 
 <div class='cpmf'><h3>cpmfKey5:</h3>cpmfValue5<br /></div> 
</div>
```

Hi @diondesigns,

Stumbled upon this to resolve html tags <div class="cpmfWrapper"> desired for wrapping <div class="cpmf"> not sure how I brain farted on this.

Is there a more elegant way of executing this operation?
```
echo '<div class="cpmfWrapper">'; 
  foreach( $cpmf as $cpmfKey => $cpmfValue ){
    ${$cpmfKey} = $cpmfValue;
      if( ! empty( $cpmfValue) ){
        echo "<div class='cpmf'><h3>{$cpmfKey}:</h3>$cpmfValue</div>";
    }
  }
echo '</div>';
```
Updating post for future reference.
