    <p>So currently I am using a 3rd party software application to get results from various surveys. This application is sending the results to a page via a $_POST variable.</p> <p>So for example..</p> <pre><code>$demoEMP = $_POST['demoEMP']; </code></pre> <p>This just stores the answer from the specific question into a variable.</p> <p>What I want to do is store Questions 1-20 in POST variables and Insert them into a database.. What I don't want to do is write 20+ Insert commands or 20+ $var = $_POST['var'] </p> <p>So I was thinking a for loop would do the trick... This is what I have so far... based on looking at various methods and tutorials. =/</p> <pre><code>for ($i = 0; $i &lt; 55; $i++) { $answer = "Q{$i}"; echo $_POST[$answer]; } </code></pre> <h2>Am I even on the right track? Thanks for your help!</h2> <p>UPDATE:: Kas' solution worked great.</p> <p>I used something like this...</p> <pre><code>foreach ($_POST as $i =&gt; $v) { if (preg_match("/^Q\d+$/",$i)) { // Here we insert value $v to database $query_2 = mysql_query("INSERT INTO SGresult VALUES ('', '', '$pID', '$SGQID','$v')") or die('Error: '.mysql_error ()); </code></pre> <p>} }</p> <p>However, I am now trying to figure a way to add an ID to the question and have that ID auto increment... on every insert. I thought I could do something like $SGQID++ but that does not seem to be working.. anyone have any thoughts?</p> <p>Thanks again!</p> <p>okay after some more tinkering it seems the placement of the ++ was off and it needed to be after the query... the correct code is as follows.</p> <pre><code>$SGQID= 1; foreach ($_POST as $i =&gt; $v) { if (preg_match("/^Q\d+$/",$i)) { // Here we insert value $v to database $query_2 = mysql_query("INSERT INTO SGresult VALUES ('', '', '$pID', '$SGQID','$v')") or die('Error: '.mysql_error ()); $SGQID++; //added value to increment Question ID in DB } } </code></pre>

    1. COyes, you are almost on right track. you can use count($_POST) instead of 55. also foreach could be used with a $counter variable.

    2. COThe code you posted can use few sanity checks but it'll work.

    3. COUsing a foreach() over the $_POST array and filtering on the key names is a better solution, because using a for loop with count($_POST) assumes you number the $_POST variables consecutively, and that no other variables are passed to your script.

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.
