    <p>I have a table where the user can add rows to it but each row is numbered. Now the user enters a number in a textbox for the number of rows he/she wants to add before they actually start adding rows. Below is the code where if the number of rows that has been added is over the number entered by the user, then it stops adding the rows.</p> <pre><code>if (qnum &gt; &lt;?php echo (int)@$_POST['textQuestion']; ?&gt;) { return; } </code></pre> <p>Example: if user entered in the number 5 in a textbox, then the user can only add 5 rows, if the user tries to add another row, then no row is added because user can't add more than 5 rows.</p> <p>Now the above works fine. But then what I want to do is that when the number of rows added has met its limit, then I want it to disable the textarea on top so i changed the code to this below:</p> <pre><code> if (qnum &gt; &lt;?php echo (int)@$_POST['textQuestion']; ?&gt;) { $('#questionTextArea').attr('disabled', 'disabled'); return; } </code></pre> <p>The problem is that if I do the code above then it disables the textarea straight away which is incorrect. What should happen is that it should allow the user to add the maximum table rows it is allowed to add and when the user reaches that limt, then disable the textarea. Does anyone know how to achieve this?</p> <p>Below is the function where it adds table rows:</p> <pre><code>function insertQuestion(form) { if (qnum &gt; &lt;?php echo (int)@$_POST['textQuestion']; ?&gt;) { $('#questionTextArea').attr('disabled', 'disabled'); return; } var $tbody = $('#qandatbl &gt; tbody'); var $tr = $("&lt;tr class='optionAndAnswer' align='center'&gt;&lt;/tr&gt;"); var $qid = $("&lt;td class='qid'&gt;" + qnum + "&lt;/td&gt;"); $tr.append($qid); $tbody.append($tr); $(form).find('.numberOfQuestions').val(qnum); ++qnum; } </code></pre> <p>Below is the textarea I want to disable:</p> <pre><code>&lt;table id="question"&gt; &lt;tr&gt; &lt;td rowspan="3"&gt;Question:&lt;/td&gt; &lt;td rowspan="3"&gt; &lt;textarea id="questionTextArea" rows="5" cols="40" name="questionText"&gt;&lt;/textarea&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </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.
