Retrieve images according to ID in mysqli - php

I wanted to retrieve machine image pass by id. But issue is that i would be getting all machine images instead of particular one. So please guide me what's wrong i have done.
<?php
$query1=mysqli_query($con,"select * from photo where m_id = $m_id");
while($row=mysqli_fetch_array($query1)){
?>
<img src="<?php echo $row['location']; ?>" height="150px;" width="150px;">
<?php
}
?>

You should filter data using WHERE to fetch only certain rows.

Just Add:
$m_id = $_POST['m_id'];
$query1=mysqli_query($con,"select * from photo where m_id = $m_id ");
hope this help

Click on an image stored in a MySQL database table and get additional row content for that image

I have created a members.php page that connects to a database table. The table has the following fields: id, username, profile image.
The following PHP code displays the profile image for each user in rows of 6 and allows each image to be clickable.
<?php
// The code below will display the current users who have created accounts with: **datemeafterdark.com**
$result=mysql_query("SELECT * FROM profile_aboutyou");
$row1 = mysql_fetch_assoc($result);
$id = $row1["id"];
$_SESSION['id'] = $id;
$profileimagepath = $row1["profileimagepath"];
$_SESSION['profileimagepath'] = $profileimagepath;
$count = 0;
while($dispImg=mysql_fetch_array($result))
{
if($count==6) //6 images per row
{
print "</tr>";
$count = 0;
}
if($count==0)
print "<tr>";
print "<td>";
?>
<center>
<img src="<?php echo $dispImg['profileimagepath'];?>" width="85px;" height="85px;">
</center>
<?php
$count++;
print "</td>";
}
if($count>0)
print "</tr>";
?>
This is all great, however, when I click on the image that loads it re-directs me to: viewmemberprofile.php which is what it is supposed to do. But it always displays the same image with the same id value (i.e.) 150 no matter which image I click. What I would like to have happened is. If I click on an image with id 155 etc... it will display content for that image data field not consistently the same image data regardless of which image I click.
Your help and guidance would be greatly appreciated. Thank you in advance.
One thing that I forgot to mention is that I do use sessions so... when I am re-directed to the viewmemberprofile.php page I use the following code to aide in getting the data that I need from the table.
<?php
$id = $_SESSION['id'];
echo($id);
?>
<?php
echo('<br>');
?>
<?php
$profileimagepath = $_SESSION['profileimagepath'];
?>
<img src="<?php echo($profileimagepath);?>" width="50px;" height="50px;">
I have yet to impliment the suggested solution.
You need to pass the ID of the row to viewmemberprofile.php, e.g.:
<a href="viewmemberprofile.php?id=<?= $dispImg['profileimagepath'] ?>">
And viewmemberprofile.php needs to select that row from the DB:
SELECT * FROM profile_aboutyou WHERE id = $_GET['id']
The above SQL statement is pseudo-code; you need to write actual code to accomplish what it is describing, preferably using parameterized queries.

how to display a photo from database base on its id to another page

I have a huge problem and been having a hard time figuring it out.I want to pass down the image id i click on onto the 2nd page.The 2nd page then uses the id and echos out an image,image_text based on what i gave in the database.
1st page
while ($row = mysqli_fetch_assoc($result)) {
echo "<div class='img-single'>
<a href='images/fpage.php?image_id={$row['image_id']}'><img class='i'
src='images/".$row['image']."' ></a>
<figcaption class='figcaption'>".$row['image_text']."</figcaption>
</div>";
}
?>
2nd page
<?php
$image_id = $_GET['image_id'];
?>
So after passing the image id in a a href='somepage.php&image_id=$image' tag. On the 2nd page use: if (isset($_GET['image_id'])) { $pic_id = $_GET['image_id'] Then make a select from database using pic_idmysqli_query($dbc, "SELECT picture, name from table_name WHERE picture_id = '$pic_id' LIMIT 1;"); echo the picture in image tags and your done.
<img src="<?php echo $picture; ?>" alt="<?php echo $name; ?>">} // Close if(issset()) I hope this helps.

Displaying specific image and MySql information when clicked on

I am building an image uploading website. Images are uploaded to a directory on the server and data such as the filename is stored in a MySql table. I have created a 'gallery' page which displays all the uploaded images as thumbnails. When a user clicks on one of the images, it takes them to 'image.php' page, which will display the image full size and echo information such as the username of the person who uploaded the image etc.
I am unsure as to what would be the correct way of displaying the image. The images in my MySql table have unique ID's which I'm guessing will have to be manipulated in some way, but how do I would I get the ID of the photo that has been clicked on into the 'image.php' MySql query?
Hope this has been explained well enough. Thanks in advance.
gallery.php page... (exclusing database connections etc.)
//Retrieves data from MySQL
$data = mysql_query("SELECT * FROM photos");
//Puts it into an array
while($info = mysql_fetch_array( $data ))
{
?>
<section class="thumbnails group">
<?php Echo "<img src=http://.../thumbs/tn_".$info['filename'] .">"; }?>
</section>
image.php page...
//Retrieves data from MySQL
$data = mysql_query("SELECT * FROM photos WHERE 'id' = ??");
//Puts it into an array
while($info = mysql_fetch_array( $data ))
{
?>
<section class="main-image group">
<?php echo "<img src=http://.../images/".$info['filename'] .">"; }?>
</section>
You can simply pass the ID of the image through in the querystring
<img src="/path/to/thumbnail">
In your image.php page, you can retrieve the ID like this (assuming it's an integer):
$imageID = intval( $_GET["image"]);
You should then be able to retrieve the path to the image and display it.
# liquorvicar answer is correct one, there's no ambiguity in his answer! well,
try this;
<?php Echo "<img src=http://...thumbs/tn_".$info['filename'] .">"; }?>
on image.php page
$id=intval($_REQUEST['id'])
now you have id for that specific image show its related info.

php display image

I am not able to display image using this code. Could any one help me in correcting?
<?php
include("connect.php");
$sql="select * from profile where userid=3";
$row=mysql_query($sql);
header("Content-type: image/jpeg");
echo $row['image'];
?>
Try
<?php
include("connect.php");
$sql = "SELECT * FROM profile WHERE userid='3'";
$row = mysql_fetch_assoc(mysql_query($sql));
echo '<img src="'.$row['image'].'" />';
?>
Depends how your information is stored in the database. If you have stored the path to a picture, this will be the right way. If you have stored the whole picture, this must be done another way.
Have you tried this way:-
echo "<img src=\"".$row['image']."\">";

PHP catalog, click on item image to display product details

I am trying to build a simple catalog displaying items from a mysql database.
So far I can get the items to display in a list format including the images stored as a path in the items table in a field called "path".
I would like the ability to be able to click on the item image and it takes you to a dedicated page showing you the details of that product. The link would correspond to which ever item you click on based on the data in the item table.
So far I have the following code;
<?php
session_start();
require "connect.php";
$date = date("d-M-Y");
$query = "select * from item order by date && time asc limit 0,3";
$query2 = "select * from users where userid = ".$_SESSION['userid'];
$result = #mysql_query($query, $connection)
or die ("Unable to perform query<br>$query");
?>
<?php
while($row= mysql_fetch_array($result))
{
?>
<?php echo $row['item'] ?>
<?php echo $row['description'] ?>
//Code for Image Link
<a href='<a href='<?php echo $row['path']?>'><img src="<?php echo $row['path']?>
<?php
}
?>
The above code allows you to click on the image and it takes me to http://127.0.0.1/steal/%3Ca%20href=
However I don't know what I would need to enter in order for it to take me to a page that shows the product?
Please Help
Many Thanks
I don't know your database schema, so I'm taking some liberties here about your columns for the product. But, try this:
<img src="<?php echo $row['path']?"/>
I also am not sure what your product page URL is either, so change product_page.php to whatever template you are using to display your products.
You need to create another page called for example showProductsOrder.php that accepts the orderID and then does output the content.
showProductsOrder.php?orderID=1
<?php
SELECT * FROM order WHERE orderID = $_GET['orderID']
while(fetch()) {
//> Show product here
}
?>
Also please don't use mysql_query. Use php.net/pdo
Addendum
Show all products
As yes123 said you would need to create another page, but i if you have a problem creating the link here is my suggested solution:
Replace your link with:
<?php echo ("<a href='".$row['pagePath']."'><img src='".$row['imagePath']."' /></a>";?>
$row['pagePath'] is the page that it will load when the image is clicked on, and
$row['imagePath'] is where the image is stored on your pc / server.
