Here is the code that allows uploading images to the root of the website. It is a submenu page in admin area that calls a function and the function body is bellow:
<div class="wrap">
<h2>Upload files</h2><br><br><br>
<form action="" method="post" enctype="multipart/form-data">
<input type="file" class="button" name="fileToUpload" id="fileToUpload">
<input type="submit" class="button button-primary" value="Upload File" name="submit">
</form>
</div>
<?php
// Check if image file is a actual image or fake image
if(isset($_POST["submit"])) {
$target_dir = get_home_path();//wp_upload_dir();
$target_file = get_home_path() . '/' . basename($_FILES["fileToUpload"]["name"]);
$uploadOk = 1;
$imageFileType = strtolower(pathinfo($target_file,PATHINFO_EXTENSION));
$check = getimagesize($_FILES["fileToUpload"]["tmp_name"]);
if($check !== false) {
?>
<div id="setting-error-settings_updated" class="updated settings-error notice is-dismissible">
<strong>File is an image</strong>
</div>
<?php
$uploadOk = 1;
} else {
?>
<div id="setting-error-settings_updated" class="updated settings-error notice is-dismissible">
<strong>File is not an image</strong>
</div>
<?php
$uploadOk = 0;
}
// Check if file already exists
if (file_exists($target_file)) {
?>
<div id="setting-error-settings_updated" class="updated settings-error notice is-dismissible">
<strong>File already exists.</strong>
</div>
<?php
$uploadOk = 0;
}
// Check file size
if ($_FILES["fileToUpload"]["size"] > 500000) {
?>
<div id="setting-error-settings_updated" class="updated settings-error notice is-dismissible">
<strong>Your file is too large.</strong>
</div>
<?php
$uploadOk = 0;
}
// Allow certain file formats
if($imageFileType != "jpg" && $imageFileType != "png" && $imageFileType !=
"jpeg"
&& $imageFileType != "gif" ) {
?>
<div id="setting-error-settings_updated" class="updated settings-error notice is-dismissible">
<strong>Sorry, only JPG, JPEG, PNG & GIF files are allowed.</strong>
</div>
<?php
$uploadOk = 0;
}
// Check if $uploadOk is set to 0 by an error
if ($uploadOk == 0) {
?>
<div id="setting-error-settings_updated" class="updated settings-error notice is-dismissible">
<strong>Sorry, your file was not uploaded.</strong>
</div>
<?php
// if everything is ok, try to upload file
} else {
if (move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $target_file)) {
?>
<div id="setting-error-settings_updated" class="updated settings-error notice is-dismissible">
<strong>The file has been uploaded.</strong>
</div>
<?php
} else {
echo "Sorry, there was an error uploading your file.";
}
}
}
I want to allow these file types instead of images: .xml, .rar, .zip, .txt. I tried to change the function getimagesize() with the function getfilesize() and to change file extensions bellow the // Allow certain file formats comment. But it doesn't work. Do you have any idea what should I do to allow uploading these file types instead of file types that are currently enabled to upload?
