i have this database which contains tables one for questions and the other for answers and i need to use php to update the question and answers but when i do query to select the question and answers i get four questions and four answers or one question and one answer here's my tables structure
------------------------------------------------------- ---------------------
| question | | answers |
------------------------------------------------------- ---------------------
PHP server scripts are surrounded by delimiters, which?| | <&>...</&>
| | <?php>...</?>
| | <script>..</script>
| | <?php...?>
here's my complete code
<?php include ("connection.php"); ?>
<?php

Well the problem is in your while cycles. The code is not very clean, but you are printing for every question 4 times the same answer (last found in your mysql database) and not all the answers. Can you try this, I am not sure if there is not a typo because I can not run the code.

I've tried a million different ways, and this is probably something super simple, but I can't get it figured out.
I have a database that displays several different columns (name, age, gender, breed, player, etc.)
What I would like is to include a line that states "We have ___ number of female characters."
Here is my entire page where I want it displayed:

Here is example for the same you can edit this
<?php
$cnt = 0;
$query = "select * from table";
$resulr = mysql_query($query);
while($var = mysql_fetch_array($result)){
if($var['gender']=='female'){
$cnt++;
}
}
echo "We have ".$cnt." female characters";
?>
SELECT COUNT(id) FROM characters where gender = 'female'
That will get you the count of characters which have 'female' as the value for gender. Is that what you want?

You could use AJAX for it. I see you use jQuery, so a simple get or post-request should do the trick.
Here: jQuery .get you will find some examples on how to do this. After the item has been added to the database you can use jQuery to add it to your select-box.
The app.php is getting the post value from another page. And that value used for query purposes. That post value is used to edit multiple values in app.php. I post again the multiple values to edit.php to update the records that shows in app.php. What I want is when I back into app.php using <meta http-equiv="refresh" content="0;app.php" /> or <script type="text/javascript">window.history.go(-1);</script> the value in app.php should get the new or the updated value from edit.php. I'm not good using sessions. Help please?
app.php
$mysqli = new mysqli("localhost", "root", "", "app");
ob_start();
session_start()
<form name="myform" method="post" action="edit.php"/>
if (isset($_POST['submit'])) {
//unset the session value
$_SESSION['content'] = '';
$drop = $_POST['drop_1'];
$tier_two = $_POST['tier_two'];
$where = "WHERE a.app_cn='$drop' AND a.app_plan_no='$tier_two'";
$result1 = $mysqli->query(" query ");
<table>
while ($row = $result1->fetch_assoc()) {
<td><input name="checkbox[]" type="checkbox" id="checkbox[]" value="' . $row['id'] . '"'.($row['pr'] == ""?"disabled ":"").' style="cursor:pointer;" class="checkbox"></td>
}

if you are using javascript to return the page it may keep the previous data. It was because our browser have the cache.
You may use
<META HTTP-EQUIV="CACHE-CONTROL" CONTENT="NO-CACHE">
and
<META HTTP-EQUIV="EXPIRES" CONTENT="Mon, 22 Jul 2002 11:12:01 GMT">
to disable the cache

On this site I found a lot of cool examples of PHP OOP.
Maybe you know where to find complete examples?
Guest books, registration forms, blog...
When I look at the full model is much easier to understand OOP PHP.
