I'm making a page which needs to display all the rows stored in a table named 'events' in a database named 'school'
The problem is that even though I've multiple entries/rows in the table, for some reason only a single row is displayed when I run the page.
Here's my code-
<?php
require("includes/common.php");
$query = "SELECT * FROM school.events";
$result = mysqli_query($con, $query)or die(mysqli_error($con));
$row = mysqli_fetch_array($result);
$ename = $row['name'];
$place = $row['place'];
$date = $row['date'];
?>
.
.
.
<?php
while ($row) {
?>
<tr>
<td><?php echo $date; ?></td>
<td><?php echo $ename; ?></td>
<td><?php echo $place; ?></td>
</tr>
<?php
$row = mysqli_fetch_array($result);
$name = $row['name'];
$place = $row['place'];
$date = $row['date'];
}
?>
Try instead while($row = mysqli_fetch_assoc($result)){ ... } , you're just assigning the array to $row, you can't loop an array saying while($array)
Do it this way:
while($row = mysqli_fetch_assoc($result)){
echo $row['id'];
echo $row['name'];
}
That is because $row = mysqli_fetch_array($result); will only pull one row and then move the pointer. In order to get all the rows, use a while loop
while($row = mysqli_fetch_array($result)) {
//code to populate table one row at a time
}

I inserted the data in the table very well and it's showing in phpMyadmin but when i try to display data from the database only one single item is displayed. I need help.
Code and screenshoots below
<?php
$sql = "SELECT * FROM nw";
$result = mysqli_query($conn, $sql);
if($result == TRUE){
$count = mysqli_num_rows($result);
if($count > 0){
while($row = mysqli_fetch_assoc($result)){
$incidentId = $row['id'];
$icTypeName = $row['inctype_name'];
$addedBy = $row['added_by'];
$addedOn = $row['added_on'];
}
?>
<tr class="tableData">
<td><?php echo $incidentId;?></td>
<td><?php echo $icTypeName;?></td>
<td><?php echo $addedBy;?></td>
<td><?php echo $addedOn;?></td>
<td><i class="uil uil-edit icon editIcon"></i></td>
</tr>
<?php
} else {
$_SESSION['noData'] = 'No incidents to show!';
}
} else {
die('Failed to Connect!');
}
?>
Images below
I expect to get all the data in the database tables displayed with the "SELECT * FROM nw"
Simply move the } that ends the while loop to after the code that is using the variables. You are currently consuming all the resultset before outputting anything, so you will only see the last rows data.
<?php
$sql = "SELECT * FROM nw";
$result = mysqli_query($conn, $sql);
if($result == TRUE){
$count = mysqli_num_rows($result);
if($count > 0){
while($row = mysqli_fetch_assoc($result)){
$incidentId = $row['id'];
$icTypeName = $row['inctype_name'];
$addedBy = $row['added_by'];
$addedOn = $row['added_on'];
//} REMOVED
?>
<tr class="tableData">
<td><?php echo $incidentId;?></td>
<td><?php echo $icTypeName;?></td>
<td><?php echo $addedBy;?></td>
<td><?php echo $addedOn;?></td>
<td><i class="uil uil-edit icon editIcon"></i></td>
</tr>
<?php
} // END OF WHILE LOOP
} else {
$_SESSION['noData'] = 'No incidents to show!';
}
} else {
die('Failed to Connect!');
}
?>
I currently have this code set up:
$sql = "SELECT * FROM homework WHERE class = '$class'";
$result = mysqli_query($conn, $sql);
$data_exist = false;
if (mysqli_num_rows($result) > 0) {
// output data of each row
$data_exist = true;
while($row = mysqli_fetch_assoc($result)) {
$id = $row["id"];
$teacher_set = $row["teacher_set"];
$class = $row["class"];
$name = $row["name"];
$description = $row["description"];
}
}
And then:
<?php if ($data_exist){?>
<p><?php echo $id ?></p>
<p><?php echo $teacher_set?></p>
<p><?php echo $name?></p>
<p><?php echo $description?></p>
<?php
}?>
However, the issue is if there is multiple results in the database it only outputs one of them, how can I prevent this from happening and output two?
I want to make it so every row has their own section, like this: http://prntscr.com/hcgtqn so if there is only one result, one one will show etc.
You have to echo data in a loop. Right now you are reassigning values in while($row = mysqli_fetch_assoc($result)) iterations and printing just the last one.
You need to print each time you read a row from the database.
about the styles, you can represent it in many ways. In the code below I present it in a table.
<table>
<thead>
<tr>
<th>id</th>
<th>teacher set</th>
<th>name</th>
<th>description</th>
</tr>
</thead>
<tbody>
<?php
$sql = "SELECT * FROM homework WHERE class = '$class'";
$result = mysqli_query($conn, $sql);
$data_exist = false;
if (mysqli_num_rows($result) > 0) {
// output data of each row
while($row = mysqli_fetch_array($result)) {
$id = $row["id"];
$teacher_set = $row["teacher_set"];
$class = $row["class"];
$name = $row["name"];
$description = $row["description"];
// you need to print the output now otherwise you will miss the row!
// now printing
echo "
<tr>
<td>".$id."</td>
<td>".$teacher_set."</td>
<td>".$name."</td>
<td>".$description."</td>
</tr>";
}
}
else // no records in the database
{
echo "not found!";
}
?>
</tbody>
</table>

I am trying to echo username.I have a table in which i only have USERID and then i take that USEDID and compare it in another table and ECHO USERNAME from there.But if there are 50 entries then it only echoes 25 .
here is the code
<?php while($row = mysqli_fetch_assoc($result)) {
$user_id = $row['user_id'];
$result2 = mysqli_query($conn, "select * from `users` WHERE `user_id` = '$user_id'");
$row2 = mysqli_fetch_assoc($result2);
while($row2 = mysqli_fetch_assoc($result2)){
$username = $row2['username'];
}
?>
<tr>
<td><?php echo $row['id']; ?></td>
<td><?php echo $row['user_id']; ?></td>
<td><?php echo $username; ?></td>
<td><?php echo $row['points']; ?></td>
</tr>
This above code doesnt echo anything at all in username but echo all results
If i change
$row2 = mysqli_fetch_assoc($result2);
to
$row2 = mysqli_fetch_assoc($result);
It echo everything with username but only few/half results
Other code that is in connection with this
$result = mysqli_query($conn, "select * from `lottery`");
$row = mysqli_fetch_assoc($result);
Remove this line:
$row2 = mysqli_fetch_assoc($result2)
Hello my first question here, I have a bad of trouble getting this code to work or better said how to proceed.
I have 2 tables, table 1 holds a string separated by commas, after exploding the array I want to compare the strings to another table that holds product prices related to the string.
<?php
function packages()
{
global $db;
$query = "SELECT * FROM product_package WHERE package_id > 1; ";
$result = mysqli_query($db, $query) or die('<h3>Query failed</h3>');
$rowcount = mysqli_num_rows($result);
if ($rowcount < 1)
{
return;
}
else
{
while ($row = mysqli_fetch_array($result))
{
$singles = explode(',', $row["product_ids"]);
$query2 = "SELECT product_price FROM products WHERE product_id = $single; ";
$result2 = mysqli_query($db, $query2);
?>
<tr>
<td><?php echo $row["package_id"] ?></td>
<td><?php echo $row["package_name"] ?></td>
<td><?php echo $row["product_ids"] ?></td>
<td>
EDIT
</td>
<td>
<?php
foreach($singles as $single)
{
echo $single . '<br />';
}
?>
</td>
</tr>
<?php
}
}
}
?>
How do I echo the prices that are overlapping with $single?
I would like to have the freedom to place a row entry from my database wherever i' prefer in the page. Right now, the php code that I use is as follows (it is clean working code):
<html><head></head>
<body>
<?php
$db = mysql_connect("xxx","xxx","xxx") or die("Database Error");
mysql_select_db("caisafety",$db);
$id = $_GET['id'];
$id = mysql_real_escape_string($id);
$query = "SELECT * FROM `cert_rr` WHERE `id`='" . $id . "'";
$result = mysql_query($query);
echo $row['id']; while($row = mysql_fetch_array( $result )) {
echo "<br><br>";
echo $row['basic3'];
echo $row['basic2'];
echo $row['basic1'];
}
?>
</body>
</html>
I call id through the browser Eg. http://site.com/getid.php?id=10 . But I do not have the freedom to place my row entry within my html. For eg. like this:
<table><tr>
<td align="center">BASIC INFO 1: <?php echo $row['basic1']; ?></td>
<td align="center">BASIC INFO 2: <?php echo $row['basic2']; ?></td>
</tr></table>
I can place html within echo PHP tags but then I have to clean up my html and thats a lot of work. Retaining HTML formatting would be preferred. Any help or guidelines on this would be much appreciated.
<?php
$db = mysql_connect("xxx","xxx","xxx") or die("Database Error");
mysql_select_db("caisafety",$db);
$id = $_GET['id'];
$id = mysql_real_escape_string($id);
$query = "SELECT * FROM `cert_rr` WHERE `id`='" . $id . "'";
$result = mysql_query($query);
//you need to retrieve every row and save to an array for later access
for($rows = array(); $tmp = mysql_fetch_array($result);)
{
$rows[] = $tmp;
}
//now you can use the $rows array where every you want e.g. with the code from Zhube
?>
....
<table><?php foreach($rows as $r):
<td><?php echo $r['id'] ?></td><?php endforeach ?>
</table>
By
while($row = mysql_fetch_array( $result )) {
echo "<br><br>";
echo $row['basic3'];
echo $row['basic2'];
echo $row['basic1'];
}
you save only the last row
Instead of having your HTML tags as part of the PHP variable, do something like this instead:
<table><?php foreach($row as $r):?>
<td><?php echo $r['id'] ?></td><?php endforeach ?>
</table>
