Array (
[0] => Array (
[id] => 13137
[meta_value] => Chris
[field_id] => 104
[item_id] => 4413
[created_at] => 2015-06-17 17:00:21
)
[1] => Array (
[id] => 13136
[meta_value] => 0.10
[field_id] => 123
[item_id] => 4413
[created_at] => 2015-06-17 17:00:21
)
);
How would I access the meta_value (Chris) where field_id = 104?
Make use of array_search function
$key = array_search(104, array_column($array, 'field_id'));
if($key !== false)
{
echo $array[$key]['meta_value'];
}
Try this
foreach($array as $k => $v ) {
if ($v['field_id'] ==104) {
$value = $v['meta_value'];
}
}
print_r($value);
Where $array is the variable in which you have above value,
To make the code reusable, you may define a function, like the following:
<?php
$array = [
['id' => 13137, 'meta_value' => 'Chris', 'field_id' => 104, 'item_id' => 4413, 'created_at' => '2015-06-17 17:00:21' ],
['id' => 13136, 'meta_value' => 0.10, 'field_id' => 123, 'item_id' => 4413, 'created_at' => '2015-06-17 17:00:21' ],
];
function getMetaValue($arr, $field_id) {
foreach($arr as $subArr)
if($subArr['field_id']==$field_id)
return $subArr['meta_value'];
return null;
}
echo getMetaValue($array, 104); // Chris
echo getMetaValue($array, 123); // 0.10
?>
