I have a question in PHP.
I am creating a website with posts but I can't make the PHP to show just the second post (without show the first).
My code is like this:
<?php
$result = mysqli_query($dbc, "SELECT * FROM projects");
$x = 1;
while($row = mysqli_fetch_array($result)){
$nome = $row['name'];
$conteudo = $row['description'];
$imagem = $row['image'];
$imagem2 = $row['image2'];
?>
<?php static $count2 = 0; if ($count2 == "1") { break; } else { ?>
<div class="content justify" id="projects-<?php echo $x; ?>" >
<?php echo $conteudo; ?>
<?php if(!empty($imagem2)) { ?>
<img class="hide-for-small" src="images/contebt/project/<?php echo $image2; ?>">
<?php }; ?>
</div>
<?php $count2++; } ?>
<?php $x++;}; ?>
With this code I can show just the first post, but I want to show just the second. Can anybody help me, please? Thanks!
This should work with this code :
PHP
<?php
$result = mysqli_query($dbc, "SELECT * FROM projects");
$x = 0;
while($row = mysqli_fetch_array($result)) {
$nome = $row['name'];
$conteudo = $row['description'];
$imagem = $row['image'];
$imagem2 = $row['image2'];
if (!$x) {
$x = 1;
continue;
}
?>
<div class="content justify" id="projects-<?php echo $x; ?>" >
<?php echo $conteudo; ?>
<?php if(!empty($imagem2)) { ?>
<img class="hide-for-small" src="images/contebt/project/<?php echo $image2; ?>">
<?php } ?>
</div>
<?php
$x++;
}
?>
SQL
But you should directly espace the first row directly in mysql usign either limit :
$result = mysqli_query($dbc, "SELECT * FROM projects LIMIT 1, 1");
or where statement :
$result = mysqli_query($dbc, "SELECT * FROM projects where id > 1");

I have the following code. How do I show the first image in the database with index of 0 for the large image display at end of the code? Right now it is showing the last image in the database.
<div id="imgWheel" class="treatmentContainer">
<?php
$query = "SELECT * FROM images WHERE user = 0 ORDER BY id;";
$result = $mysqli->query($query);
while ($row = $result->fetch_array(MYSQLI_ASSOC)) {
$product = $row["product"];
$room = $row["room"];
$style = $row["style"];
$tags = $row["tags"];
$src = $row["url"];
$dataid = $row["id"];
$imgClass = "";
if (in_array($src, $favourites)) {
$imgClass = " favourite";
}
echo "<div class='treatment$imgClass' data-url='$src' data-product='$product' data-room='$room' data-style='$style' data-tags='$tags' data-number='$dataid' id='pic_$dataid' >";
echo "<img src='$src' crossorigin='anonymous'/>";
echo "</div>";
}
?>
</div> <!-- close imgWheel -->
<!-------- Large Image Display------- -->
<div id="display">
<img id="mainImage" src="<?php echo $src ?>" />
</div>
Your result set is alreadyx ordered by id, so you need only a variable, to be filled once with the first imageurl
<div id="imgWheel" class="treatmentContainer">
<?php
$bigpictureurl = "";
$query = "SELECT * FROM images WHERE user = 0 ORDER BY id;";
$result = $mysqli->query($query);
while ($row = $result->fetch_array(MYSQLI_ASSOC)) {
$product = $row["product"];
$room = $row["room"];
$style = $row["style"];
$tags = $row["tags"];
$src = $row["url"];
$dataid = $row["id"];
if (empty($bigpictureurl)) {
$bigpictureurl = $src ;
}
$imgClass = "";
if (in_array($src, $favourites)) {
$imgClass = " favourite";
}
echo "<div class='treatment$imgClass' data-url='$src' data-product='$product' data-room='$room' data-style='$style' data-tags='$tags' data-number='$dataid' id='pic_$dataid' >";
echo "<img src='$src' crossorigin='anonymous'/>";
echo "</div>";
}
?>
</div> <!-- close imgWheel -->
<!-------- Large Image Display------- -->
<div id="display">
<img id="mainImage" src="<?php echo $bigpictureurl ?>" />
</div>
You just need to update your SQL query, just add LIMIT 1. This will limit the result just to 1 record and as you have ORDER id ASC, it will show the first record of the given user (as per you it is 0).
$query = "SELECT * FROM images WHERE user = 0 ORDER BY id ASC LIMIT 1;";
A quick and dirty solution is to save your first image in some separate variables, for example like this:
$isFirst = true;
$firstImageSrc = "";
$result = ....;
while (...) {
// set your $product, $room etc here
if ($isFirst) {
$isFirst = false;
$firstImageSrc = $src;
}
}
echo ...
?>
</div> <!-- close imgWheel -->
<!-------- Large Image Display------- -->
<div id="display">
<img id="mainImage" src="<?php echo $firstImageSrc ?>" />
</div>
A much more elegant solution would be to create an array with all your images, so that you can separate your php from your html. I will refactor your code below, and fix your first image problem as well:
<?php
$images = [];
$idx = 0;
$query = "SELECT * FROM images WHERE user = 0 ORDER BY id;";
$result = $mysqli->query($query);
while ($row = $result->fetch_array(MYSQLI_ASSOC)) {
$images[$idx]["product"] = $row["product"];
$images[$idx]["room"] = $row["room"];
$images[$idx]["style"] = $row["style"];
$images[$idx]["tags"] = $row["tags"];
$images[$idx]["src"] = $row["url"];
$images[$idx]["dataid"] = $row["id"];
$images[$idx]["imgClass"] = "";
if (in_array($src, $favourites)) {
$images[$idx]["imgClass"] = " favourite";
}
$idx++;
}
?>
<div id="imgWheel" class="treatmentContainer">
<?php foreach ($images as $image) { ?>
<div class='treatment<?=$image["imgClass"]?>' data-url='<?=$image["src"]?>' data-product='<?=$image["product"]?>' data-room='<?=$image["room"]?>' data-style='<?=$image["style"]?>' data-tags='<?=$image["tags"]?>' data-number='<?=$image["dataid"]?>' id='pic_<?=$image["dataid"]?>' >
<img src='<?=$image["src"]?>' crossorigin='anonymous'/>
</div>
<?php } ?>
</div> <!-- close imgWheel -->
<!-------- Large Image Display------- -->
<div id="display">
<img id="mainImage" src="<?=$images[0]["src"]?>" />
</div>
Since you have all of that in your WHILE statement, I assume you want to echo all those records. And then at the end show the 1st pic. So for the "Large Image Display," give this a try:
<div id="display">
$query = "SELECT * FROM images WHERE user = 0;";
$result = $mysqli->query($query);
$row = $result->fetch_array(MYSQLI_ASSOC)
$src = $row["url"];
<img id="mainImage" src="<?php echo $src ?>" />
</div>
If you'd like less code, then save the value of $src inside your WHILE loop when user=0 into some other variable like $src2. And then your code simply becomes:
<img id="mainImage" src="<?php echo $src2 ?>" />

I just want for example paste detected link to <a> element and then write some meta information like in ATTACHMENT upper
I have a nested div in which I want to fetch data from my database. I have explained what I want below:
<div class="row-fluid">
<div class="span6">
**First Entry Here**
</div>
<div class="span6">
**Second Entry Here**
</div>
</div>
<div class="row-fluid">
<div class="span6">
**Third Entry Here**
</div>
<div class="span6">
**FourthEntry Here**
</div>
</div>
and so on...
I am literally confused right now and the solution is not clicking in my mind. I have this code so far:
$sql = "SELECT * FROM `users`";
$result = mysqli_query($conn, $sql);
$ic = 0;
while ($row = mysqli_fetch_assoc($result)) {
if(($ic%2) == 0) {
$div1 = '<div class="row-fluid">';
$div2 = '</div>';
}else{
$div1 = '';
$div2 = '';
}
?>
<?=$div1;?>
<div class="span6">
<?=$row['userid'];?>
</div>
<?=$div2;?>
<?php
$ic = $ic + 1;
}
?>
I have tried two while loops but it was outputting around 5000 lines of code.
$ic = 0;
$temp = "";
while ($row = mysqli_fetch_assoc($result)) {
$temp .= "<div class='span6'>".$row['user_id']."</div>";
if ( $ic % 2 != 0 ){
echo "<div class='row-fluid'>".$temp."<div>";
$temp = "";
}
$ic++;
}
// in case the number of records are odd::
if ($temp != "" )
echo "<div class='row-fluid'>".$temp."<div>";
#Amr Magdy logic is correct, however the solution didn't work out for me. I have now managed to fix it and if anyone else has the same situation may refer to the code below:
<?php
$sql = "SELECT * FROM `users`";
$result = mysqli_query($conn, $sql);
$ic = 0;
$temp = "";
while ($row = mysqli_fetch_assoc($result)) {
$temp = '<div class="span6">'.$row['userid'].'</div>';
if(($ic%2) == 0) {
echo '<div class="row-fluid">'.$temp;
$temp = "";
}else{
echo $temp;
}
$ic = $ic + 1;
}
echo '</div>';

I've got a table called tickets. The Tickets table has 4 columns: user_id, ticket_id, subject, message. I want to loop the ticket_id and subject of the logged in user. I want to echo it with foreach, but I cant get it to work. This is what I've got:
Query:
$showTheTickets = array();
$user_id = $_SESSION['user_id'];
$getTickets = mysqli_query($mysqli,"SELECT * FROM tickets WHERE user_id = '$user_id'") OR die (mysqli_error($mysqli));
while($row = mysqli_fetch_assoc($getTickets)){
$showTicketID = $row['ticket_id'];
$showTicketSubject = $row['subject'];
}
Code in the page:
<?php foreach ($showTheTickets as $showTheTickets): ?>
<div class="preview">
<?php echo $showTicketID ?>
<?php echo $showTicketSubject ?>
</div>
<?php endforeach; ?>
Anyones willing to help me? Thanks.
Try this:
$showTheTickets = array();
$user_id = $_SESSION['user_id'];
$getTickets = mysqli_query($mysqli,"SELECT * FROM tickets WHERE user_id = $user_id") OR die (mysqli_error($mysqli));
while($row = mysqli_fetch_array($getTickets)){
$row = array( 'ticket_id' => $row['ticket_id'], 'subject' => $row['subject'] );
$showTheTickets[] = $row;
}
And then:
<?php foreach ($showTheTickets as $stt): ?>
<div class="preview">
<?php echo $stt['ticket_id'] ?>
<?php echo $stt['subject'] ?>
</div>
<?php endforeach; ?>
Hope it helps...
You are overwriting the values you get from the query and your $showTheTickets array remains empty.
You probably want something like:
$showTheTickets = array();
while($row = mysqli_fetch_assoc($getTickets)){
$showTheTickets[$row['ticket_id']] = $row['subject'];
}
and:
<?php foreach ($showTheTickets as $id => $subject): ?>
<div class="preview">
<?php echo $id; ?>
<?php echo $subject; ?>
</div>
<?php endforeach; ?>
Why not simply
while($row = mysqli_fetch_assoc($getTickets)){
?><div class="preview"><?
echo $row['ticket_id'];
echo $row['subject'];
?></div><?
}
you have to save $showTicketID and $showTicketSubject in a array (could be the same array or 2 arrays) and then in the view show the arrays, like this:
while($row = mysqli_fetch_assoc($getTickets)){
$array[$row['ticket_id']] = $row['subject'];
}
and the view:
<?php foreach ($showTheTickets as $ticketid => $ticketsubject): ?>
<div class="preview">
<?php echo $ticketid ?>
<?php echo $ticketsubject ?>
</div>
<?php endforeach; ?>
I have the following code:
$result = mysqli_query($con, "SELECT * FROM da_questions");
while($row = mysqli_fetch_array($result))
{
}
mysqli_close($con);
which selects everything from the table da_questions. Now this is in a file called config.php which file is required in all my pages of my website. Now I want to do the following on my external pages... let's say index.php
<?php foreach($results as $question): ?>
<p><?php echo $question['question_title']; ?></p>
<br />
<p><?php echo $question['question_text']; ?></p>
<br />
<?php endforeach; ?>
My file outlay is like shown below:
index.php
config/
config.php
How can I do this?
Why not just
$results = array(); while($row = mysqli_fetch_array($reult)) { $results[] = $row; }
or as #Phil pointed out:
$results = $result->fetch_all(MYSQLI_ASSOC)
With your code
$result = mysqli_query($con, "SELECT * FROM da_questions");
$results = array();
while($row = mysqli_fetch_array($result))
{
$results[] = $row;
}
mysqli_close($con);
in the index.php write as below
include('config/config.php');
<?php foreach($results as $question): ?>
<p><?php echo $question['question_title']; ?></p>
<br />
<p><?php echo $question['question_text']; ?></p>
<br />
<?php endforeach; ?>
