Show price after selected a element in drop list
<p>Long ago, I search all over the web but I was unable to find a solution that suits me. I have to write what I want the forum to find help that suits me.</p>

<p>To begin, I have a drop-down which offers several choices. Here is the list</p>

<pre><code>&lt;Form name = "sellalcatel" form method = "post" action = "traitement.php" onchange = "return vefify ();"&gt;
    &lt;Select name = "Alcatel"&gt;
        &lt;Option&gt; Please Select &lt;option&gt;
        &lt;Option value = "Alcatel-1230 + ZTE811"&gt; Alcatel 1230 (ZTE 811) &lt;/ option&gt;
        &lt;Option value = "Alcatel-1231"&gt; Alcatel 1231 &lt;/ option&gt;
        &lt;Option value = "Alcatel-351"&gt; Alcatel 351 &lt;/ option&gt;
    &lt;/ Select&gt;
    &lt;Li class = "last"&gt;
        Country &lt;input type = "text" size = "40"&gt;
        &lt;P&gt; Name &lt;INPUT NAME = "Name" SIZE = 40&gt; &lt;/ p&gt;
        &lt;P&gt; Enter your Mail &lt;input name = "email" placeholder = "mail@example.com" required&gt; &lt;/ p&gt;
        &lt;Input name = "button" type = "submit" value = "unlock"&gt; &lt;/ input&gt;
    &lt;/ Li&gt;
&lt;/ Form&gt;
</code></pre>

<p>I want that after the selection of the drop-down list to display the price depending on the selection: for example, if the customer chose the first that should show $ 3 usd, if the second Usd $ 4, $ 2 for the third usd so on.</p>

<p>NB ~ I want to recover the money but simply display it without reloading the page, many of the sites proposed to make a BDD but my problem is that I do not know how to put the price in the database and also the attribute to its correct value in the dropdown.</p>

<p>So is there any other solutions to display the price or can I get help or a database like I want to aficher price?</p>
