    <p>I have a problem with my application. First of all on a previous page the teacher types in the number of sessions (exams) he or she wants to create and types in the number of questions they want per session.</p> <p>Now on the current page, If I have multiple sessions or exams in other words, then lets say I am on the first exam, it will let me add question numbers for the first exam. Now If I submit the form then it will take me to the second session and I have to add new question numbers in from scratch. Now if I try to add a question number a question number, then it does not add a question number into the table.</p> <p>I have figured out where the problem occurs. The problem occurs in the code below:</p> <pre><code>if (qnum &gt; &lt;?php echo (int)@$_POST['textQuestion']; ?&gt;) { return; } </code></pre> <p>What I have stated above is that if the number of questions added, is more than the number of questions stated on the previous page, then do not add question number. So lets say I have 2 sessions and I want only 1 question per session. In the first session it adds question number 1, but when I get to second session, it doesn't add question number 1 for second session because it thinks it is question number 2, even though it is suppose to be question 1 for second session. </p> <p>So how do I get it so that if user goes to second session, it knows that the question number starts back at 1?</p> <p>Below is full code on how question number is added into a table:</p> <pre><code> var qnum = 1; var count = 1; function insertQuestion(form) { if (qnum &gt; &lt;?php echo (int)@$_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); count++; $(form).find('.numberOfQuestions').val(qnum); ++qnum; $("#questionNum").text(qnum); } </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.
