I have created a database namely newwork and table name property. In this database I have stored user details and one image. Now I want to display all the data from one field and stored image from the same field in a new page. Please help me for this program. The fields are property_id, property, location, image.
You really need two parts here (one to build the HTML and another to fetch/display the image):
Part 1: HTML builder
<?php
$res = mysqli_query($cnx, 'SELECT property_id, property, location from newwork';
if (res)
{
while ($row = mysqli_fetch_assoc($res))
{
echo '<span class="property">'.$row['property'].'</span>';
echo '<span class="location">'.$row['location'].'</span>';
echo '<span class="photo"><img src="image.php?id='.$row['property_id'].'" /></span>
}
}
Part 2: Image builder
<?php
$res = mysqli_query($cnx, 'SELECT image
FROM newwork
WHERE property_id='.intval($_REQUEST['id']));
if ($res)
{
$row = mysqli_fetch_assoc($res);
if (!empty($row))
{
header('Content-Type: image/jpg');
echo $row['image'];
exit;
}
}
header('Location: error_image.jpg',TRUE,302);

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.
See Table of report data
The table is as displayed in the image above. I wanted to display all the data including several images for which URLs are saved in the imageURL column separated with a semicolon.
The number of image URLs differs in each columns.
The URLs refer to image path in upload folder as shown below:
InvestigatorsReportApi/uploads/KBC589L-1.jpg;
InvestigatorsReportApi/uploads/KBC589L-2.jpg;
InvestigatorsReportApi/uploads/KBC 589L-3.jpg;
How would I display this in a website?
You should simmply make a query about the URL:
$sql = "SELECT url FROM table";
$result = $conn->query($sql);
After that echo it into the <img> tag src attribute:
while($row = $result->fetch_assoc()) {
echo "<img src='".$row["url"]."'>";
}
And there you have it. The sample code above will print every image in the database.
Just try this
$sql = "SELECT url FROM table";
$result = $conn->query($sql);
while($row = $result->fetch_assoc()) {
foreach(explode(';',$row["url"]) as $image) {
echo "<img src='".$image."'>";
}
}
First fix your table. It is bad. You should let the attributes occupy the first row:
id: name: LOA: regNO: rout..., then
first you need to use explode function for separate your image url
$image=explode(";",$imageURL);
then use foreach loop for display image
foreach($image as $value)
{
<img src='".$value."'/>
}
I'm creating a website where users will need to be able to upload images, and I'd like them to be able to delete those images. Right now, I have a page that will display all of the images that that user has uploaded, and I have a php set up to delete an image from the database. It just needs to be given the id of the image. I have it functioning with the GET method, but I'm concerned a user could find the URL for my delete php and put in random ids, deleting everyone's images. Is there a way I can adjust my code to make it safer?
<?php
$sql = "SELECT id, userid, name, image FROM images";
$result = mysqli_query($conn, $sql);
if (mysqli_num_rows($result) > 0) {
// output data of each row
while($row = mysqli_fetch_assoc($result)) {
if ($imageUser == $row["userid"]){
echo "<tr>";
echo "<th>".$row["userid"]."</th>";
echo "<th>".$row["name"]."</th>";
echo "<th><img src='showimage.php?id=".$row["id"]."'></th>";
echo "<th><a href='imgdelete.php?id=".$row["id"]."'>delete</a></th>";
echo "</tr>";
}
}
} else {
echo "0 results";
}
?>
The delete.php simply deletes the entry WHERE id=$_GET['id'];
In a RESTful API, a GET request should never modify the data. If you want to delete items, you should use a POST or a DELETE request.
Im trying to add images to my database by using an image path, under the Image column, i have used varchar as the the type and i have inserted images/canin.jpg as the value.
When im trying to display this image using php it doesn't work, this is what i have :
$sql = "SELECT dog_id, dogbreed, image, sellercontact, location FROM dog";
$result = $conn->query($sql);
if ($result->num_rows > 0) {
echo "<table><tr><th>ID</th><th>Dog Breed</th><th>Image</th><th>Seller and Contact number</th><th>Location</th></tr>";
// output data of each row
while($row = $result->fetch_assoc()) {
echo "<tr><td>".$row["dog_id"]."</td><td>".$row["dogbreed"]." <td>".$row["image"]."</td><td>".$row["sellercontact"]." </td><td>".$row["location"]."</td></tr>";
}
echo "</table>";
} else {
echo "0 results";
All the other information such as dog it, dog breed etc is being retrieved, but its not bringing back the image.
any ideas?
You need to use the HTML img tag to display the image.
Replace <td>".$row["image"]."</td> with <td><img src=\"".$row["image"]."\"/></td>
This should produce <td><img="images/canin.jpg"/></td> when executed
I'm trying out my hand at php at the moment - I'm very new to it!
I was wondering how you would go about selecting all items from a mySQL table (Using a SELECT * FROM .... query) to put all data into an array but then not displaying the data in a table form. Instead, using the extracted data in different areas of a web page.
For example:
I would like the name, DOB and favorite fruit to appear in one area where there is already say 'SAINSBURYS' section hardcoded into the page. Then further down the next row that is applicable to 'ASDA' to appear below that.
I searched both here and google and cant seem to find an answer to my strange questions! Would this involve running the query multiple times filtering out the sainsburies data and the asda data where ever I wanted to place the relevant
echo $row['name']." ";
echo $row['DOB']." "; etc etc
next to where it should go?
I have got php to include data into an array (I think?!)
$query = "SELECT * FROM people";
$result = mysql_query($query) or die(mysql_error());
$row = mysql_fetch_array($result) or die(mysql_error());
while($row = mysql_fetch_assoc($result))
{
echo $row['name']." ";
echo $row['DOB']." ";
echo $row['Fruit']." ";
}
?>
Just place this (or whatever your trying to display):
echo $row['name']." ";
Anywhere you want the info to appear. You can place it within HTML if you want, just open new php tags.
<h1>This is a the name <?php echo $row['name']." ";?></h1>
If you want to access your data later outside the while-loop, you have to store it elsewhere.
You could for example create a class + array and store the data in there.
class User {
public $name, $DOB, $Fruit;
}
$users = new array();
$query = "SELECT * FROM people";
$result = mysql_query($query) or die(mysql_error());
while($row = mysql_fetch_array($result)) {
$user = new User;
$user->name = $row["name"];
$user->DOB = $row["DOB"];
$user->Fruit = $row["Fruit"];
$users[$row["name"]] = $user;
}
Now you can access the user-data this way:
$users["USERNAME"]->name
$users["USERNAME"]->DOB
$users["USERNAME"]->Fruit
