I need help.i have this database
student_code: 1234
student_id: angel
namaFoto: angel.jpg
using GET method to call specific data from database, i use this code below, but the data doesn't show up. what did i do wrong?
<?php
include_once "library/inc.sesadmin.php";
$row = 25;
$hal = isset($_GET['hal']) ? $_GET['hal'] : 1;
if($usertype != 'Admission'||$usertype != 'Administrator'){
if($_GET) {
$Kode = $_GET['Kode'];
$myQry=$db->prepare("SELECT * FROM student WHERE student_code='$Kode'");
$myQry->execute();
$myQryCount = $myQry->rowCount();
while ($myData = $myQry->fetch()) {
}
}
?>
<table >
<tr>
<td ><img src="foto/<?php echo $namaFoto; ?>"></td>
<td ><b>Code</b></td>
<td ><b>:</b></td>
<td ><?php echo $myData['student_code']; ?></td>
</tr>
<tr>
<td><b>Student ID </b></td>
<td><b>:</b></td>
<td> <?php echo $myData['student_id']; ?> </td>
</tr>
</table>
<?php } else { ?>
<br /> <br /> <br /> <br /> <br /> <br />
<p align="center">You are not authorized to access this area</p>
<?php } ?>
Are you including ?Kode=1234 on the URL you are using to access the page? Also the image isn't using the same $myData collection to retrieve the image value. That may not be a root-cause issue, but does look to be a big.

How can you pass dynamic details which are retrieved from a database (e.g. details in a shopping cart table) from one page to another page so that you could send them via email using the mail() function?I tried many ways using the "$message" but none worked. I am new to PHP and do not have much experience with it yet. Any help would be appreciated, thank you.

Please specify what you have tried so far.
you want to send the data from one page to another, try using form tag in html
and set the method attribute to post and action attribute to where you want to send the data.
The html code will look like this
<form action="post" action="getdata.php"> <input id="val" type="text" value="" name="cart" style="display:none;"> <button type="submit" >hit me</button> </form>
You can set the value of input using javascript
document.getElementById("val").value="YourValue";
getdata.php will look like this
> if ($_SERVER["REQUEST_METHOD"] == "POST"){
> $cartval=$_POST['cart'];
> echo $cartval; }
be sure to validate the data and check for any hidden code before executing the user input
I have my current code working perfectly but I needed help on when I want the code to display as many queries exist in the table called wine... for example if there are more than wine type in category as spain then it should display all but it only displays one.
Here is my PHP:
<?php
include"db_connection.php";
$sql = mysql_query("SELECT * FROM WINE WHERE country='Chile'");
while($row = mysql_fetch_array($sql)){
$description = $row["description"];
$wine_type = $row["wine_type"];
$country = $row["country"];
$bottle_price = $row["bottle_price"];
$indicator = $row["indicator"];
$colour = $row["colour"];
$case_price = $row["case_price"];
$case_size = $row["case_size"];
$date_added = strftime("%b %d, %Y", strtotime($row["date_added"]));
}
?>
Here is my HTML:
<?php include('header.php'); ?>
<div id="content">
<table width="100%" border="0" cellspacing="0" cellpadding="15">
<tr>
<td width="19%" valign="top"><img src="inventory_images/<?php echo $id; ?>.jpg" width="142" height="188" alt="<?php echo $wine_type; ?>" /><br />
View Full Size Image</td>
<td width="81%" valign="top"><h3><?php echo $wine_type; ?></h3>
<p><?php echo "$".$bottle_price; ?><br /><br />
<?php echo "$country $indicator"; ?> <br /><br />
<?php echo $description; ?> <br />
</p>
<form id="form1" name="form1" method="post" action="cart.php">
<input type="hidden" name="pid" id="pid" value="<?php echo $id; ?>" />
<input type="submit" name="button" id="button" value="Add to Shopping Cart" />
</form>
</td>
</tr>
</table>
</div>
<?php include('footer.php'); ?>
The problem is currently that the while() loop will keep overriding the variables. This can be solved in a couple of ways, one would be that you save the entire fetched column in an array and use that array later for iteration.
$allRows = array();
while($row = mysql_fetch_array($sql)) {
$allRows[] = $row;
}
Now, as mentioned above, iterate over $allRows in your template
<?php include('header.php'); ?>
<div id="content">
<table width="100%" border="0" cellspacing="0" cellpadding="15">
<?php
foreach ($allRows as $row) {
?>
<tr>
<td width="19%" valign="top"><img src="inventory_images/<?php echo $row['id']; ?>.jpg" width="142" height="188" alt="<?php echo $row['wine_type']; ?>" /><br />
etc.
</tr>
<?php
}
?>
</table>
</div>
<?php include('footer.php'); ?>
Here I addressed the variables as $row['...'] - if you don't want to change that part of the code, simply do the assigning at the beginning of the loop.
etc.
<?php
foreach ($allRows as $row) {
$description = $row["description"];
$wine_type = $row["wine_type"];
//etc.
?>
A much cleaner solution (not mixing that much HTML and PHP which usually creates lots of confusion) would be using a template engine. Also don't use mysql_* functions in new code - they are deprecated. See this answer for more information.
I am building an application that gives user the opportunity to click on the day of the calendar and when there is an activity registered on that day, it shows a table with the activity registered...my problem is that when there is no activity on that day, I wont it to return the string : There is no activity.. I try to make it using if($nrofrows>0)like below but all the time it returns me the string :there is not activity, even I have activity on that day.
Please can you help me ? where is my error? Thanks in advance...

Might be a problem with the query you can add this to see:
$result= mysql_query("SELECT * FROM Aktiviteti where Data= '$_POST[dataoutput]' and Perd_Id='$perdoruesi'") or die ("query error" .mysql_error());
mysql_num_rows($result) returns false when there is an error so you might want to add this:
if($nrofrows && $nrofrows>0)
try this
if ( mysql_num_rows($result) > 0 ) {
}
I have a page that contains an ordering form, on this form it lists the vendor information and then each of the products for the vendor underneath and in front of the product is an input field that allows the user to input the quantity of each product that they want.
Upon submitting the information goes to a confirmation page where I need to be able to show the order information. On the form on the order page, I have a hidden field that contains the vendor id. and the vendor id is put once for each vendor. What I need to be able to do is not only echo out the quantity but also echo out the vendor id specific for each order. My code is below. The first block is the order page and then the block below that will be the confirm page.
As it stands right now underneath every quantity it displays all the vendor ids as opposed to just the one I need.

This is the confirm page below.

$db= Loader::db();
$quantity = $_POST['quantities'];
$vendor = $_POST['vendor'];
$minimumorder = 25;

foreach($vendor as $vendors){

I appreciate any help anyone can give. This has had me stumped for a few days actually.
you might want to rearrange your array, and do something like:
$i = 0;
foreach ($productresults as $product) {
echo '<input name="product['.$i.'][quantity]" />';
echo '<input name="product['.$i.'][vendor_id]" value="'.$vendor['vendorID'].'" type="hidden" />';
++$i;
}
The resulting array in $_POST would have the quantities & their vendor separated into their own arrays.
In your code $vendor['vendorID'] seems the key of your $_POST['quantities'] so in your confirm page you could use:
foreach($quantity as $vendorid=>$num){
if ($num >= $minimumorder){
echo "$num";
echo "</br>";
echo "$vendorid";
}
}
I am dynamically loading question content into a div using jquery . This is my first attempt and it does load when I click the "Get Question"-button. However, the "Get Question"-button disappears when the question loads. I want the button to stay and eventually use it as a next question button.
Here is the jquery code:
<script type="text/javascript" src="../jquery/jquery/jquery-1.7.2.js"></script>
<script type="text/javascript">
$(document).ready(function(){
$(
$("#GetQuest").click(function(){
$.post("CCRN/question.php", {num : parseInt($("input#q_num").val()) + 1}, function (data) {
$("div#question").html(data);
$("input#q_num").val() = parseInt($("input#q_num").val()) + 1;
});
});
});
</script>
<input type="button" id="GetQuest" value="Get Question" />
<input type="hidden" id="q_num" value=1 />
<p>Question: <div id="question"> </div></p>
<p>Answer: <div id="answer"> </div></p>
Here is the question creating code (though the question loads and display fine)
<table width="100%"><?php
$i = $q_num;
if ($row["image"] <> NULL) { ?>
<tr align="center">
<td colspan="2" align="center">
<img src="<?php $pic = $row["image"]; echo $base_path . $pic; ?>" />
</td>
</tr><br />
<tr>
<td colspan="3"> </td>
</tr>
<?php
} ?>
<tr id="Qu<?php echo $i; ?>" class="Qu<?php echo $i; ?>">
<td width="7%"><?php echo $i.") " ?></td>
<td width="93%" ><?php echo $row["question"]; ?></td>
</tr>
<?php
for ($j=1;$j<=6;$j++) {
$bracket= "answer_" . $j;
if ($row[$bracket] !== NULL) {?>
<tr>
<td align="center" class="row<?php echo $j % 2; ?>" width="7%">
<input type="radio" <?php echo ($_POST["Q".$i] == $j) ? 'checked="checked"' : '' ; ?> name="Q<?php echo $i; ?>" value="<?php echo $j; ?>" /><?php echo chr(64 + $j); ?>
</td>
<td class="row<?php echo $j % 2; ?>" width="93%">
<?php echo $row["answer_".$j]; ?>
</td>
</tr> <?php
}
} ?>
</table><hr size="2" width="95%">
I do not understand why the button disappears when I load the question content. I am SURE it is something embarassing simple, which is why I am coming to a safe haven to minimize the ridicule! :)
Live test site http://www.GrowingSpeakers.com/index2.php to see the disappearing button.
You are using div with id "question" before.
<div class="TabbedPanelsContent" id="question">
and
<p>Question: <div id="question"> </div></p>
It does not matter even though the id's come from different files as long as they are displayed in the same DOM tree - they will be treated as one and the same.
You have 2 div's with the ID question and the javascript is going to replace the content of the first one found when you run:
$("div#question").html(data);
if you change the id for the first one it should work fine.
