    <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>What my question is that if the user has already reach the max number of rows they have added, then I want it to disable a textarea (user wont be able to click in the textarea and I want to give it the correct colour so that you can tell the textarea is disabled). I also want to disable a hyperlink so that user cannot click on the hyperlink (again suitable color change so user can tell hyperlink is disabled) Does anyone know how to do this?</p> <p>Below is code for hyperling and the textarea:</p> <pre><code> &lt;table id="question"&gt; &lt;tr&gt; &lt;th colspan="2"&gt; Question Number &lt;span id="questionNum"&gt;1&lt;/span&gt; &lt;/th&gt; &lt;/tr&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;span href="#" class="link"&gt;[Question link]&lt;/span&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </code></pre> <p>Jquery code showing example of how a table row is added:</p> <pre><code>function insertQuestion(form) { var questionarea=(form.questionText.length) ? form.questionText[0] : form.questionText; var context = $('#optionAndAnswer'); var currenttotal = context.find('.answerBtnsOn').length; alertErrors = ""; // Note, this is just so it's declared... if (questionarea.value == ""){ if (qnum &gt; &lt;?php echo (int)@$_POST['textQuestion']; ?&gt;) { 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); } </code></pre> <p>Html table where the table row is added to:</p> <pre><code>&lt;table id="qandatbl" align="center"&gt; &lt;thead&gt; &lt;tr&gt; &lt;th class="qid"&gt;Question No&lt;/th&gt; &lt;/tr&gt; &lt;/thead&gt; &lt;tbody&gt;&lt;/tbody&gt; &lt;/table&gt; </code></pre> <p>look at this jsfiddle for example <a href="http://jsfiddle.net/DQUKN/42/" rel="nofollow">here</a>, you can write a question on top using the textarea and when you have done that then click on the button to add it in a new row. It is the top textarea I want to disable only if the number of rows has met its limit.</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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
