I'm making a personal website and I just wanted it to be a bit easier for me to add/edit my posts without manually going into phpmyadmin.
When I go to the edit_post.php page and press update I get an "=" sign next to the pid eg.(foo.php?pid=3), and if i let it redirect to the blog page it doesn't update it.

You have to set the columns and set the values for the columns.
UPDATE posts SET ( title, content, img, date ) VALUES ($title, $content, $img, $date) WHERE id = $pid;
$date = date("l jS \of F Y h:i:s A");
use instead of above line
$date = date('Y-m-d H:i:s', strtotime());
$sql = 'UPDATE posts SET title='".$title."', content='".$content."', img='".$img."', date='".$date."' WHERE id='".$pid."'";
Ok so I figured it out, very small programmers blindness but hey we all get it.
Line 66 echo "<form action='edit_post.php?pid$pid' method='post' enctype='multipart/form-data'>";
Where it says "?pid$pid" I just needed to remove the "=" that i had there.

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 have a page that displays the display of an item with a specific id and I want to display other items that are related based on title, subject, or author. I am having issues with displaying related items. Where I put my query together and execute it, the related results are just the same title of the item whose page I am already on (https://brawlins.com/soarOpen/itemRecord.php?id=65437). How do I displays related results that are not the same as the item whose page I currently am on?

Hello so i made my filter system its a simple one only location and price range are set for now everything looks like this :
so the problem i have is that min and max price range filter doesn't work location filter are working as it should be the only problem i face is min and max price got no error or warning nothing but eater nothing happens to.
php code above :
$cat1 = '';
if(isset($_GET["catid"])){
$p1 = '';
$p2 = '';
$catid = $_GET["catid"];
$l1 = substr($catid,0,1);
$l2 = substr($catid,1,1);
$p1 = "CAT".$l1;
if(!empty($l2)){
$p2 = "CAT".$l1."-".$l2;
$p3 = $p2;
}
$cat1 = #$lang[$p1];
$cat2 = #$lang[$p2];
}

I think it's because you are treating the price as a string, in the sql query you wrote
$sql.= "AND price>='$min' ";
Try with cast/sanitize/filter input variables $min & $max to integers and removing the quotes.
--- by the way, I personally would also change some things:
use atom instead of brackets
use an ORM and remove the query from the html page (the view)
if 2 is not possible, try to move all php logic to the php file instead of the html part
remove all that IFs and try to write a code without lots of repetitions
You are also joining the tables instead of filtering, try changing
$sql = "SELECT * FROM posts p JOIN images i ON p.id = i.postid ";
with
$sql = "SELECT * FROM posts p JOIN images i ON p.id = i.postid WHERE p.id > 0 ";
change
$pricemin = '';
$pricemax = '';
with
$min = '';
$max = '';
I have a database with a few images already set, I would like to have the url display an ID from each query as the user hits next. The user should be able to share the URL and paste it into their browser, the url should pull that unique ID from the query. The issue i am having is every time i paste a url, I get a random image and not the image that is in the ID. I'm at a loss here and im not sure what to do :( here's the code I have so far.
<?php
if (isset($_GET['id'])) {
include("PHP/db.php");
echo $where = $_GET["id"];
echo $query = "SELECT * FROM images WHERE ID =" . $where;
$result = mysqli_query($dbc, $query);
$row = mysqli_fetch_array($result);
$ID = $row['ID'];
$title = $row['name'];
$image = "<img height=500 width=600 src=http://www.goupics.com/img/" . $row['name'] . " >";
}
if($_GET['next4']) {
echo 'HELLO THIS IS THE NEXT IF METHOD';
include("PHP/db.php");
$query = "SELECT * FROM images ORDER BY RAND() LIMIT 1";
$result = mysqli_query($dbc, $query);
$row = mysqli_fetch_array($result);
$ID = $row['ID'];
$title = $row['name'];
$image = "<img height=500 width=600 src=http://www.goupics.com/img/" . $row['name'] . " >";
}
?>
<body>
</div>
<div id="title"> <?php echo $title ?> </div>
<div id="mainpic">
<?php echo $image ?>
</div>
<div id="prevnext">
<div id="next">
<a href="?id=<?php echo $ID ?>" name="name4" >Next</a>
</div>
<div id="prev">
Previous
</div>
</div>
Try this:
<?php
include("PHP/db.php");
$query2 = "SELECT * FROM images ORDER BY RAND() LIMIT 1";
$result2 = mysqli_query($dbc, $query2);
$rand_row = mysqli_fetch_array($result2);
$rand_id = $rand_row ['ID'];
if (!isset($_GET['id'])) {
$_GET['id'] = $rand_id;
}
if (isset($_GET['id'])) {
echo $where = $_GET["id"];
echo $query = "SELECT * FROM images WHERE ID =" . $where;
$result = mysqli_query($dbc, $query);
$row = mysqli_fetch_array($result);
$ID = $row['ID'];
$title = $row['name'];
$image = "<img height=500 width=600 src=http://www.goupics.com/img/" . $row['name'] . " >";
}
?>
<body>
</div>
<div id="title"> <?php echo $title ?> </div>
<div id="mainpic">
<?php echo $image ?>
</div>
<div id="prevnext">
<div id="next">
<a href="?id=<?php echo $rand_id; ?>" name="name4" >Next</a>
</div>
<div id="prev">
Previous
</div>
</div>
I changed:
-link to next is now id=rand
-changed your code to give me a "rand ID" and its already defined on the href of the page you load
It will go inside condition (next == true).
Make sure that your variables are initialized before use.
