How do I add images to my PHP blog? - php

Question

I have made a blog for my website with PHP and mysql database, where I can add blog posts from an admin site (www.website.com/admin) and display them on my website (www.website.com). It's working fine, but I want to add pictures too.
This is my code for adding:
if (isset($_POST['submit'])) {
$blogtitle = htmlentities($_POST['blogtitle'], ENT_QUOTES);
$blogdate = htmlentities($_POST['blogdate'], ENT_QUOTES);
$blogdesc = htmlentities($_POST['blogdesc'], ENT_QUOTES);
// check that firstname and lastname are both not empty
if ($blogtitle == '' || $blogdesc == '') {
$error = 'Please fill in all required fields';
renderForm($blogtitle, $blogdesc, $error);
} else {
// insert the new record into the database
if ($stmt = $mysqli->prepare("INSERT blog_posts (blogtitle, blogdate, blogdesc) VALUES (?, ?, ?)")) {
$stmt->bind_param("sss", $blogtitle, $blogdate, $blogdesc);
$stmt->execute();
$stmt->close();
} else {
echo "ERROR: Could not prepare SQL statement.";
}
header("Location: website.php");
}
} else {
renderForm();
}
}
// close the mysqli connection
$mysqli->close();
And my code for display the blog posts
/.../
while ($row = $result->fetch_object()) {
echo "<div>";
echo "<td>" . $row->blogtitle . "</td>";
echo "<td>" . $row->blogdate . "</td>";
echo "<td>" . $row->blogdesc . "</td>";
echo "</div>";
}
I know how to make an upload.php, but is it easier to upload to mysql? I dont know how to get the image shown in the right blogpost after uploading.

Answer 1

You can upload the file to the server and then store the filename in your database, for example a column named "blogimg".
Then in your code for displaying blog posts you can add this line to show the image:
echo "<td><img src='" . $row->blogimg . "' /></td>";

Answer 2

you need to upload images to a directory and save images name in a database
after that right the url of the image in img tag and get the image name from the database
your html form
<form action="upload.php" method="post" enctype="multipart/form-data">
Select image to upload:
<input type="file" name="fileToUpload" id="fileToUpload">
<input type="submit" value="Upload Image" name="submit">
</form>
your php code
<?php
$target_dir = "uploads/";
$target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]);
$uploadOk = 1;
$imageFileType = pathinfo($target_file,PATHINFO_EXTENSION);
// Check if image file is a actual image or fake image
if(isset($_POST["submit"])) {
$check = getimagesize($_FILES["fileToUpload"]["tmp_name"]);
if($check !== false) {
echo "File is an image - " . $check["mime"] . ".";
$uploadOk = 1;
} else {
echo "File is not an image.";
$uploadOk = 0;
}
}
?>
