    <p>I would like to know how to retrieve a selected value from a dynamically selection box. If I get the selected value then I will store it into another variable that is located in another php file. This variable will help me in a sql query in postgresql.</p> <p>//First php file</p> <pre><code> &lt;form name="boton_alta_soniador" action="dar_alta_soniador.php" method="POST" autocomplete="off"&gt; &lt;div class="text-field"&gt; Nombre de la asociacion &lt;? $strconn="dbname=postgres port=5432 host=127.0.0.1 user=xxx password=xxx"; $conn=pg_Connect($strconn); $consulta="Select n_asociacion from asociacion"; $result=pg_query($conn,$consulta); while($results [] =pg_fetch_object($result)); array_pop($results);?&gt; &lt;select name="asociacion_seleccion" id="i_clave_asociacion"&gt; &lt;?php foreach ( $results as $option ) : ?&gt; &lt;option value="&lt;?php echo $option-&gt;i_clave_asociacion; ?&gt;"&gt;&lt;?php echo $option-&gt;n_asociacion; ?&gt;&lt;/option&gt; &lt;?php endforeach; ?&gt; &lt;/select&gt; &lt;/div&gt; &lt;/form&gt; </code></pre> <p>This is just the dynamically selection box. Then I want to store the selected value in this variable: </p> <pre><code>$ingresaAsociacion = pg_escape_string($_POST['asociacion_seleccion']); </code></pre> <p>So I can query the following statement:</p> <pre><code>$conocerIDasociacion = "SELECT N_ASOCIACION FROM ASOCIACION WHERE I_CLAVE_ASOCIACION='$ingresaAsociacion'"; </code></pre> <p>I didn't want to use jQuery because the whole system is almost entirely made in PHP and HTML. Please, any help is welcome and I'm all ears to everyone. </p> <p>Cheers!</p>

    1. COYou'll need to use some javascript to get the value and AJAX to send it back to the server.

    2. COThank you for your answer, however, I don't know nothing about AJAX, though. Is it necessary to use AJAX?

    3. COYou will either need AJAX or some other way to send an HTTP request to your server (like a form submission). I know you said you don't want to use it, but jQuery would make this process easier.

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.
