get field echoing json

Hi,

I’ve a function to return the table inside a repeater field with the following code:
```
if ( have_rows( $repeater_name ) ) {
	while ( have_rows( $repeater_name ) ) { the_row();
		$table = get_sub_field('content_table'));
	}
}
```
If I var dump the table sub_field I get:

string(69) "{"p":{"o":{"uh":0}},"c":[{"p":""}],"h":[{"c":""}],"b":[[{"c":"aa"}]]}"

Everything is ok, except that, using the documentation provided I expected to be an array, so I can use the cycles described in the plugin description.

Am I doing something wrong?

Thanks

Your code is ok.

May there went something wrong with the PHP json_decode() function in your server environment. Please test the following code that should decode the JSON string to an array…
```
var_dump( json_decode( '{"p":{"o":{"uh":0}},"c":[{"p":""}],"h":[{"c":""}],"b":[[{"c":"aa"}]]}', true ) );
```
It should output this…
```
array(4) { ["p"]=> array(1) { ["o"]=> array(1) { ["uh"]=> int(0) } } ["c"]=> array(1) { [0]=> array(1) { ["p"]=> string(0) "" } } ["h"]=> array(1) { [0]=> array(1) { ["c"]=> string(0) "" } } ["b"]=> array(1) { [0]=> array(1) { [0]=> array(1) { ["c"]=> string(2) "aa" } } } }
```

Hi Johann, thanks for the quick reply! 🙂

The code you provided outputted the correct array (as you wrote).

This is my complete code:

single-post page (inside the loop):
```
$product = new SG_products;
$product->getProductRepeater('measurements', 'content_table', get_the_ID()));
```
SG_products class:
```
public function getProductRepeater( $repeater_name, $field_name, $product_id ) {
	if ( have_rows( $repeater_name ) ) {
		$descriptions = array();
		while ( have_rows( $repeater_name ) ) { the_row();
			foreach (get_sub_field('taxonomy_association') as $taxonomy_group) {
				$descriptions[$taxonomy_group][$field_name]	= $this->getTable( $field_name );
			}
		}
	}
	return $descriptions;
}

private function getTable( $field_name ) {
	$field = get_sub_field($field_name);
	var_dump($field);
	$table = '<table>';
	foreach ( $field['body'] as $tr ) {
		$table .= '<tr>';
		foreach ( $tr as $td ) {
			$table .= '<td>';
			$table .= $td['c'];
			$table .= '</td>';
		}
		$table .= '</tr>';
	}
	$table .= '</table>';
	return $table;
}
```
The output of the var_dump is the json I wrote in the first post.
Any thoughts?

Thanks for the help!

There are to many ) at the end in line…
```
$product->getProductRepeater('measurements', 'content_table', get_the_ID()));
```
Anyway, I tested this class and it worked as expected.

Hi Johann,

I’ve found the error. I’m using a local wp install but with an remote database (dev env). I forgot to sync the plugin folder…
In the admin area everything was ok (since I access it remotely), but testing locally, the wp installation didn’t find the plugin, hence the error…

Sorry for the inconvenience, I need the weekend asap 😛

Thanks once again and keep up the great work!
