add alt for images in a while statement - php

Question

Can anyone help please?
This is my code.I want to add an alt option for images but everything I try is throwing errors.
I have tried studying the php handbook and have tried copying code from other questions but so far no luck.
<?php
$servername = "localhost";
$username = "logosewe_5";
$password = "password";
$dbname = "logosewe_5";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$sql = "SELECT * FROM mk2";
$sql = "SELECT * FROM mk2 WHERE brand='2786'";
$result = $conn->query($sql);
if ($result->num_rows > 0) {
// output data of each row
while($row = $result->fetch_assoc()) {
echo '<img src='$row['ming']'>';
}
} else {
echo "0 results";
}
$conn->close();
?>

Answer 1

You have a string concatenation problem :
echo '<img src="' . $row['ming'] . '">';
Will output : <img src="myimage.jpg">.
To add a alt attribute, you could do :
echo '<img src="' . $row['ming'] . '" alt="' . $row['name'] . '">';
Will output something like
<img src="myimage.jpg" alt="image name">

Answer 2

change your code like this:
<?php
$servername = "localhost";
$username = "logosewe_5";
$password = "password";
$dbname = "logosewe_5";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$sql = "SELECT * FROM mk2"
;
$sql = "SELECT * FROM mk2 WHERE brand='2786'";
$result = $conn->query($sql);
if ($result->num_rows > 0) {
// output data of each row
while($row = $result->fetch_assoc()) {
echo '<img src="'.$row['ming'].'" alt="'.$altText.'">'; //change here
}
} else {
echo "0 results";
}
$conn->close();
?>

Answer 3

The problem was that you did not have an alt attribute in your echo statement and the second was your concatenation was a little off with misplaced quotes.
while($row = $result->fetch_assoc()) {
echo '<img src=' . $row['ming'] . 'alt="Your alt message">';
}
