    <p>Let's say i have this form:</p> <pre><code> &lt;form method="post" name="b" &gt; &lt;table&gt; &lt;tr&gt; &lt;td&gt;Field A&lt;/td&gt; &lt;td&gt;&lt;input type='text' name='field[0][a]' id='field[0][a]'&gt;&lt;/td&gt; &lt;td&gt;Field B&lt;/td&gt; &lt;td&gt;&lt;textarea name='field[0][b]' id='field[0][b]'&gt;&lt;/textarea&gt;&lt;/td&gt; &lt;td&gt;&lt;button&gt;remove&lt;/button&gt;&lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; &lt;/div&gt; &lt;div id="container"&gt;&lt;/div&gt; &lt;button id="mybutton"&gt;add form&lt;/button&gt; &lt;div align="center"&gt; &lt;p&gt;&lt;button onClick="dadosFormulario()" value="Registar" name="registar"&gt;Registo&lt;/button&gt;&lt;/p&gt; &lt;/div&gt; &lt;/form&gt; </code></pre> <p>and i have a jquery function that duplicates the inputs i have when i click the "add form" button. So, regarding that, i'm trying to save the values of the inputs with the .val() method of jquery.</p> <p>So, if i have an input like this one:</p> <pre><code>&lt;input type='text' name='teste' id='teste'&gt; </code></pre> <p>i know that with this:</p> <pre><code>var v = $('#teste').val(); </code></pre> <p>i can receive her value. However, if i have an array of inputs, and that's my situation since i can duplicate the fields of the form, how can i obtain the multiple values from the following inputs?</p> <pre><code>&lt;input type='text' name='field[0][a]' id='field[0][a]'&gt; &lt;input type='text' name='field[0][b]' id='field[0][b]'&gt; </code></pre> <p>var v = $('#field[iterator][a]').val(); won't work, it results in 'undefined'.</p> <p>jquery function where i can't get the values from the inputs with the val(); gives undefined:</p> <pre><code>$countForms = 1; (function($){ $.fn.addForms = function(idform){ var myform = "&lt;table&gt;"+ " &lt;tr&gt;"+ " &lt;td&gt;Field A ("+$countForms+"):&lt;/td&gt;"+ " &lt;td&gt;&lt;input type='text' name='field\\["+$countForms+"\\]\\[a\\]'&gt;&lt;/td&gt;"+ " &lt;td&gt;Field B ("+$countForms+"):&lt;/td&gt;"+ " &lt;td&gt;&lt;textarea name='field["+$countForms+"]['b']'&gt;&lt;/textarea&gt;&lt;/td&gt;"+ " &lt;td&gt;&lt;button&gt;remove&lt;/button&gt;&lt;/td&gt;"+ " &lt;/tr&gt;"+ "&lt;/table&gt;"; if(idform=='mybutton'){ myform = $(myform); $("button", $(myform)).click(function(){ $(this).parent().parent().remove(); }); $(this).append(myform); $countForms++; } }; })(jQuery); $(function(){ $("#mybutton").bind("click", function(e){ e.preventDefault(); var idform=this.id; if($countForms&lt;3){ $("#container").addForms(idform); } }); }); </code></pre>

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.
