    <p>I am having a problem getting a string comparison to work in PHP if I have "é" in the text. Below is the code that I have with a pile of debug inline code. What the problem is that if I select Montréal in the dropdown the <code>if</code> test doesn't work.</p> <pre><code>if ($metabox-&gt;get_the_value() == $key) echo $selected; // original code pre debug </code></pre> <p><strong>Code</strong></p> <pre><code>a= Array( [INFORMATION] =&gt; INFORMATIONS [LODGING] =&gt; HEBERGEMENT [LOOK OUT FOR] =&gt; À SURVEILLER [Montréal] =&gt; Montréal [PROMOTIONS] ==&gt; PROMOTIONS [SECTION NAME] ==&gt; NOM DE SECTION [SPOTLIGHT] ==&gt; EN VEDETTE ) foreach (a as $key =&gt; $val){ echo '&lt;option value="'.$key.'"'; if (strcasecmp ( trim($metabox-&gt;get_the_value())), trim($key))== 0) echo $selected ; echo '&gt;'.$key.' ('.$val.'):'. strcmp ( $metabox-&gt;get_the_value(), $key). '&lt;/option&gt;'; } </code></pre> <p>Output looks like this if I select and save Montréal, it is been saved in the DB.</p> <pre><code>&lt;select name="_content_language_meta[_content_cat_type]"&gt; &lt;option value="-1"&gt;Select&lt;/option&gt; &lt;option value="INFORMATION"&gt;INFORMATION (INFORMATIONS):Montréal - 1&lt;/option&gt; &lt;option value="LODGING"&gt;LODGING (HEBERGEMENT):Montréal - 1&lt;/option&gt; &lt;option value="LOOK OUT FOR"&gt;LOOK OUT FOR (À SURVEILLER):Montréal - 1&lt;/option&gt; &lt;option value="Montréal"&gt;Montréal (Montréal):Montréal - -1&lt;/option&gt; &lt;option value="PROMOTIONS"&gt;PROMOTIONS (PROMOTIONS):Montréal - -1&lt;/option&gt; &lt;option value="SECTION NAME"&gt;SECTION NAME (NOM DE SECTION):Montréal - -1&lt;/option&gt; &lt;option value="SPOTLIGHT"&gt;SPOTLIGHT (EN VEDETTE):Montréal - -1&lt;/option&gt; &lt;/select&gt; </code></pre> <p>Output if INFORMATION is selected</p> <pre><code>&lt;select name="_content_language_meta[_content_cat_type]"&gt; &lt;option value="-1"&gt;Select&lt;/option&gt; &lt;option value="INFORMATION" selected="selected"&gt;INFORMATION (INFORMATIONS):INFORMATION - 0&lt;/option&gt; &lt;option value="LODGING"&gt;LODGING (HEBERGEMENT):INFORMATION - -1&lt;/option&gt; &lt;option value="LOOK OUT FOR"&gt;LOOK OUT FOR (À SURVEILLER):INFORMATION - -1&lt;/option&gt; &lt;option value="Montréal"&gt;Montréal (Montréal):INFORMATION - -1&lt;/option&gt; &lt;option value="PROMOTIONS"&gt;PROMOTIONS (PROMOTIONS):INFORMATION - -1&lt;/option&gt; &lt;option value="SECTION NAME"&gt;SECTION NAME (NOM DE SECTION):INFORMATION - -1&lt;/option&gt; &lt;option value="SPOTLIGHT"&gt;SPOTLIGHT (EN VEDETTE):INFORMATION - -1&lt;/option&gt; &lt;/select&gt; </code></pre> <p>This is a WordPress / MYSQL site. Ideas?</p>

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.
