    <p>Here is my example array $postcodeSuppliers:</p> <pre><code>Array ( [0] =&gt; AB123 [postcode] =&gt; AB123 [1] =&gt; TEST [supplier_1] =&gt; TEST [2] =&gt; [supplier_2] =&gt; [3] =&gt; [supplier_3] =&gt; ) </code></pre> <p>I have been trying to confirm whether a supplier is empty. Here is the code I have been using for this:</p> <pre><code>function generateQuoteSuppliers($postcodeSuppliers) { $quoteSupplier = array("supplier_1", "supplier_2", "supplier_3"); //print("&lt;pre&gt;"); //print_r($postcodeSuppliers); //print("&lt;/pre&gt;"); for ($i = 1; $i &lt; 4; $i++) { $supplier = $postcodeSuppliers['supplier_' . $i . '']; //if ($supplier == '') //if (!isset($supplier)) if (empty($supplier)) { //A fake supplier is added here 'FAKE' if any of the 3 suppliers contain no date echo "NO SUPPLIER"; $quoteSupplier['supplier_' . $i . ''] = array ( 'supplier' =&gt; 'FAKE', 'price' =&gt; 0 ); } else { $quoteSupplier['supplier_' . $i . ''] = array ( 'supplier' =&gt; $postcodeSuppliers['supplier_' . $i . ''], 'price' =&gt; 0 ); } } return $quoteSupplier; } </code></pre> <p>None of the methods I have been using to check if the value is empty are working. I get this:</p> <pre><code>Array ( [0] =&gt; supplier_1 [1] =&gt; supplier_2 [2] =&gt; supplier_3 [supplier_1] =&gt; Array ( [supplier] =&gt; TEST [price] =&gt; 0 ) [supplier_2] =&gt; Array ( [supplier] =&gt; [price] =&gt; 0 ) [supplier_3] =&gt; Array ( [supplier] =&gt; [price] =&gt; 0 ) ) </code></pre> <p>When I am expecting this:</p> <pre><code>Array ( [0] =&gt; supplier_1 [1] =&gt; supplier_2 [2] =&gt; supplier_3 [supplier_1] =&gt; Array ( [supplier] =&gt; TEST [price] =&gt; 0 ) [supplier_2] =&gt; Array ( [supplier] =&gt; FAKE [price] =&gt; 0 ) [supplier_3] =&gt; Array ( [supplier] =&gt; FAKE [price] =&gt; 0 ) ) </code></pre> <p>Can someone show me where I am going wrong please? I am completely open to the fact I am wrong! or using my array incorrectly.</p>

    1. COWhat exactly do you mean by empty? Empty string?

    2. COWhere is the data coming from in the first place? Are you sure that the "empty" supplier isn't being assigned a space or something like that? You might also be able to test against `NULL` or `""` i.e. `if($supplier == NULL)`

    3. COThe initial data comes from a MySQL table. German Rumm's answer is correct. For some reason (which I will look into) the 'empty' suppliers in the first array must contain some white space. A lesson definitely learned. Much thanks.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
