Query a CTP based on Custom Field, PHP issue. WordPress

Luis Abarca comments:

I put the $tag as un array as example, i think you are getting tha $tag value from the current post tags or something like that ?

West Coast Design Co. comments:

Hi Luis,

I won't know the values of these custom field, these values will interact similar to tags.

<strong>I need:</strong>
$tag = get_post_meta($post->ID, 'cf-tag', true);

<strong>To output:</strong>
"apples, bananas,"

<strong>Inside:</strong>
'meta_values' => $tag

<em>Make sense?</em>

Luis Abarca comments:

Yep, as Arnav said, you need to change to false the last argument of get_post_meta to get an array instead of a single value.


$tag = get_post_meta($post->ID, 'cf-tag', false);


Updated:

<strong>$tag = get_post_meta($post->ID, 'cf-tag', false);</strong>
$args = array(
'post_type' => 'quotes',
'meta_query' => array(
array(
'key' => 'cf-tag',
'value' => $tag,
)
),
'orderby' => 'rand'
);

$query = new WP_Query( $args );

while( $query->have_posts() )
{
$query->the_post();
the_title();
the_content();
}

wp_reset_query();

Luis,

False outputs an Array, but doesn't seem to work with

'value' => $tag,

<em>Any suggestions, thanks for the assistance!</em>

Luis Abarca comments:

OK, so you are storing a list of values separated by comma: "apples, bananas,"

Using the code from Arnav.


$tag = get_post_meta($post->ID, 'cf-tag', true);

$tag = explode(",",$tag);

$args = array(
'post_type' => 'quotes',
'meta_query' => array(
array(
'key' => 'cf-tag',
<strong>'value' => array_values($tag),</strong>
)
),
'orderby' => 'rand'
);

Correct, nothing seems to be working lol.

Arnav Joy comments:

try this
$tag = get_post_meta($post->ID, 'cf-tag', true);

$tag = explode(",",$tag);

Arnav Joy comments:

try my first answer if you are adding multiple meta box with the same
and try my second answer if you are using single meta box with values seperated with ,

West Coast Design Co. comments:

Arnav,


Thanks! However, your second method outputs:

array ( 0 => 'demo', )

with doesn't seem to work with

'value' => $tag,

<strong>Current Code:</strong>


$tag = get_post_meta($post->ID, 'wcgi-tag', true);
$tag = explode(",",$tag);
//var_export($tag);


$args = array(

'post_type' => 'customerspotlight',
'meta_query' => array(

array(

'key' => 'wcgi-tag',
'value' => $tag,

)

),

'orderby' => 'rand'

);


$query = new WP_Query( $args );



while( $query->have_posts() )

{

$query->the_post();

the_title();

the_content();

}

wp_reset_query();

Arnav Joy comments:

did you placed a , at last in your custom filed value?

West Coast Design Co. comments:

Sadly yes :(

lol.

Arnav Joy comments:

try this

$tag = get_post_meta($post->ID, 'cf-tag', false);
$tag = explode(",",substr($tag,0,strlen($tag)-1)));

Arnav Joy comments:

try this as their was an extra) in last code...

$tag = get_post_meta($post->ID, 'cf-tag', false);
$tag = explode(",",substr($tag,0,strlen($tag)-1));

Arnav Joy comments:

if you are placing , at last then use

$tag = explode(",",substr($tag,0,strlen($tag)-1));

as this will remove last , from the string

otherwise use

$tag = explode(",",$tag);
