This blog Post concerns about Image uploading functionality using PHP and jQuery in forms. Just click on live demo or follow our codes to use it.

Here we have created an html form, set it’s attribute enctype=”multipart/form-data”. This form contains input tag , type=” file” when a user clicks on this input tag a window will opens for image file selection, after image selection an image preview is shown to user (using jquery). As user clicks on another input tag of type submit on which a PHP script will executes in which we wrote our codes in following steps:-

  • We defined an array of allowed extensions .
$validextensions = array("jpeg", "jpg", "png");
  •  Defined a variable to store the selected file extension.
$temporary = explode(".", $_FILES["file"]["name"]);
$file_extension = end($temporary);
  •  Matching selected file size and it’s extension with allowed file size and  allowed file extensions.
if ((($_FILES["file"]["type"] == "image/png")
|| ($_FILES["file"]["type"] == "image/jpg")
|| ($_FILES["file"]["type"] == "image/jpeg"))
&& ($_FILES["file"]["size"] < 100000)//approx. 100kb files can be uploaded
&& in_array($file_extension, $validextentions)){
//PHP Image Uploading Code
}
  • If it is invalid file then,
echo "<span>***Invalid file Type or file Size Exceeded***<span>";
  • Else the following code will execute:
echo "<span>Your File Uploaded Succesfully...!!</span><br/>";
echo "<br/><b>File Name:</b> " . $_FILES["file"]["name"] . "<br>";
echo "<b>Type:</b> " . $_FILES["file"]["type"] . "<br>";
echo "<b>Size:</b> " . ($_FILES["file"]["size"] / 1024) . " kB<br>";
echo "<b>Temp file:</b> " . $_FILES["file"]["tmp_name"] . "<br>";

if (file_exists("upload/" . $_FILES["file"]["name"])) {
echo $_FILES["file"]["name"] . " <b>already exists.</b> ";
}
else {
move_uploaded_file($_FILES["file"]["tmp_name"],
"upload/" . $_FILES["file"]["name"]);
echo "<b>Stored in:</b> " . "upload/" . $_FILES["file"]["name"];
}

PHP Image Uploading Script : uploadphp.php

Here, We have given complete Image Uploading Script.

<?php

if (isset($_POST['submit'])) {

$validextensions = array("jpeg", "jpg", "png");
$temporary = explode(".", $_FILES["file"]["name"]);
$file_extension = end($temporary);

if ((($_FILES["file"]["type"] == "image/png") || ($_FILES["file"]["type"] == "image/jpg") || ($_FILES["file"]["type"] == "image/jpeg")
) && ($_FILES["file"]["size"] < 100000)//Approx. 100kb files can be uploaded.
&& in_array($file_extension, $validextensions)) {

if ($_FILES["file"]["error"] > 0) {
echo "Return Code: " . $_FILES["file"]["error"] . "<br/><br/>";
} else {

echo "<span>Your File Uploaded Succesfully...!!</span><br/>";
echo "<br/><b>File Name:</b> " . $_FILES["file"]["name"] . "<br>";
echo "<b>Type:</b> " . $_FILES["file"]["type"] . "<br>";
echo "<b>Size:</b> " . ($_FILES["file"]["size"] / 1024) . " kB<br>";
echo "<b>Temp file:</b> " . $_FILES["file"]["tmp_name"] . "<br>";
if (file_exists("upload/" . $_FILES["file"]["name"])) {
echo $_FILES["file"]["name"] . " <b>already exists.</b> ";
} else {
move_uploaded_file($_FILES["file"]["tmp_name"], "upload/" . $_FILES["file"]["name"]);
$imgFullpath = "http://".$_SERVER['SERVER_NAME'].dirname($_SERVER["REQUEST_URI"].'?').'/'. "upload/" . $_FILES["file"]["name"];
echo "<b>Stored in:</b><a href = '$imgFullpath' target='_blank'> " .$imgFullpath.'<a>';

}

}
} else {
echo "<span>***Invalid file Size or Type***<span>";
}
}
?>

 

 

jQuery Code: script.js

This, jquery code is to provide image preview facility in form, before Uploading it.

$(document).ready(function() {
// Function for Preview Image.
$(function() {
$(":file").change(function() {
if (this.files && this.files[0]) {
var reader = new FileReader();
reader.onload = imageIsLoaded;
reader.readAsDataURL(this.files[0]);
}
});
});
function imageIsLoaded(e) {
$('#message').css("display", "none");
$('#preview').css("display", "block");
$('#previewimg').attr('src', e.target.result);
};
// Function for Deleting Preview Image.
$("#deleteimg").click(function() {
$('#preview').css("display", "none");
$('#file').val("");
});
// Function for Displaying Details of Uploaded Image.
$("#submit").click(function() {
$('#preview').css("display", "none");
$('#message').css("display", "block");
});
});
