i know this question is asked before but i cant figure out how to get this to work. I have a function that triggers whenever i delete a post. It will then move the file to a existing folder on the server. what i would like for it to do is to check if there is already a file with the same name in this folder. if this file exist it should append a number to this file. for example if file 1234.jpg exist it should rename the file that i want to move to 1234-1.jpg.
The code i have so far is:
add_action('before_delete_post', function ($id) {
$rs_image_path = "/var/www/html/wp-content/uploads/hexon/";
$rs_image_dest_path = "/var/www/html/wp-content/uploads/wpallimport/files/images/";
// $rs_image_filenames="30946280-1.JPG,30946280-2.JPG,30946280-3.JPG,30946280-4.JPG";
// $rs_image_klantnummer = "1232";
$rs_image_filenames = get_field('afbeeldingen_bestandsnamen', $id);
$rs_image_klantnummer = get_field('hexon_klantnummer', $id);
$variableAry = explode(", ", $rs_image_filenames);
foreach ($variableAry as $rs_image_url) {
/* Store the path of source file */
$filePath = $rs_image_path . "" . $rs_image_klantnummer . "/" . $rs_image_url;
/* Store the path of destination file */
$destinationFilePath = $rs_image_dest_path . "" . $rs_image_klantnummer . "/" . $rs_image_url;
/* Move Files */
if (!file_exists($filePath) || !is_readable($filePath)) {
// some error handling here
} else {
$b = !rename($filePath, $destinationFilePath);
}
}
}
);
How about this?
$n = '';
while (file_exists($destinationFilePath.$n) || !rename($filePath, $destinationFilePath.$n)) {
$n++;
// escape loop
if ($n > 100) {
throw new Exception('Error saving');
}
}
$destinationFilePath .= $n;

This is a dilemma I have been chipping away at. I can't seem to figure out the best approach here.
I have my server pull multiple json files to one single directory and the json files are all in the same structure. Each of the files have a randomly generated file name.
My end goal is to append certain elements of each json file to an easily readable html table.
Here is my current code that works great with a single json file:
$.getJSON('testing1.json, function(data) {
$.each(data.user.products, function () {
$("table").append($("<tr>").append(
$("<td>").addClass("Title").text(this.title),
$("<td>").addClass("Price").text("$"+this.price),
$("<td>").addClass("Stock").text(this.stock),
));
});
});
Now I need to figure out the best way to go about my issue. I have ~250 json files I need to loop through. Obviously this regex wont work but may give you an idea of what I am trying to do:
$.getJSON('*.json, function(data) {
I would prefer to not have to merge them all into one single file. But the fact all the names are randomly generated, and I don't know how to load multiple json files into my code, I am worried I will have to do this. But it wouldn't be the end of the world if this was the case.
Is it possible to use Jquery/PHP to loop through the directory and pull all the json files? If so how would one go about loading each json file to append data from?
I really appreciate the help in advance, even a push in the right direction is much appreciated.
Make a .php file and make a call to this file. In this file use php methods to load all the files starting let's say with word json from the specified directory.
That will allow you in 1 request load all files back.
Like an example, this will give a good starting point:
/**
* load all site-wide jscript_*.js files from includes/jscript, alphabetically
*/
$directory_array = $template->get_template_part($template->get_template_dir('.js',DIR_WS_TEMPLATE, $current_page_base,'jscript'), '/^jscript_/', '.js');
while(list ($key, $value) = each($directory_array)) {
echo '<script type="text/javascript" src="' . $template->get_template_dir('.js',DIR_WS_TEMPLATE, $current_page_base,'jscript') . '/' . $value . '"></script>'."\n";
}
//Load all JS files and here are the main funtions:
function get_template_part($page_directory, $template_part, $file_extension = '.php') {
$directory_array = array();
if ($dir = #dir($page_directory)) {
while ($file = $dir->read()) {
if (!is_dir($page_directory . $file)) {
if (substr($file, strrpos($file, '.')) == $file_extension && preg_match($template_part, $file)) {
$directory_array[] = $file;
}
}
}
sort($directory_array);
$dir->close();
}
return $directory_array;
}
function get_template_dir($template_code, $current_template, $current_page, $template_dir, $debug=false) {
// echo 'template_default/' . $template_dir . '=' . $template_code;
if ($this->file_exists($current_template . $current_page, $template_code)) {
return $current_template . $current_page . '/';
} elseif ($this->file_exists(DIR_WS_TEMPLATES . 'template_default/' . $current_page, preg_replace('/\//', '', $template_code), $debug)) {
return DIR_WS_TEMPLATES . 'template_default/' . $current_page;
} elseif ($this->file_exists($current_template . $template_dir, preg_replace('/\//', '', $template_code), $debug)) {
return $current_template . $template_dir;
} else {
return DIR_WS_TEMPLATES . 'template_default/' . $template_dir;
// return $current_template . $template_dir;
}
}
function file_exists($file_dir, $file_pattern, $debug=false) {
$file_found = false;
$file_pattern = '/'.str_replace("/", "\/", $file_pattern).'$/';
if ($mydir = #dir($file_dir)) {
while ($file = $mydir->read()) {
if (preg_match($file_pattern, $file)) {
$file_found = true;
break;
}
}
$mydir->close();
}
return $file_found;
}
Using glob I was able to scan and merge all .json files. Although not really ideal, it works for the most part.
<?php
$files = glob("*.json");
$newDataArray = [];
foreach($files as $file){
$thisData = file_get_contents($file);
$thisDataArray = json_decode($thisData);
$newDataArray[] = $thisDataArray;
}
$newDataJSON = json_encode($newDataArray);
file_put_contents("merged.json",$newDataJSON);
?>
I have made a form on the front end to upload some images. My idea is to automatically rename all files uploaded into unique id's.
I have looked at the SilverStripe API and I do not see anything about that. UploadField API
Is this possible?
Here is my solution bellow, in Silverstripe 3.X we must extend UploadField with another class. Then copy the ''saveTemporaryFile'' function into it.
Just before ''try'', just have to add :
$ext = array_reverse(explode('.',$tmpFile['name'])); // explode filename into array, reverse array, first array key will then be file extension
$tmpFile['name'] = hash_hmac('sha256', $tmpFile['name'], '12345') . '.' . $ext[0];
Results :
class RandomNameUploadField extends UploadField {
protected function saveTemporaryFile($tmpFile, &$error = null) {
// Determine container object
$error = null;
$fileObject = null;
if (empty($tmpFile)) {
$error = _t('UploadField.FIELDNOTSET', 'File information not found');
return null;
}
if($tmpFile['error']) {
$error = $tmpFile['error'];
return null;
}
// Search for relations that can hold the uploaded files, but don't fallback
// to default if there is no automatic relation
if ($relationClass = $this->getRelationAutosetClass(null)) {
// Create new object explicitly. Otherwise rely on Upload::load to choose the class.
$fileObject = Object::create($relationClass);
}
$ext = array_reverse(explode('.',$tmpFile['name'])); // explode filename into array, reverse array, first array key will then be file extension
$tmpFile['name'] = hash_hmac('sha256', $tmpFile['name'], '12345') . '.' . $ext[0];
// Get the uploaded file into a new file object.
try {
$this->upload->loadIntoFile($tmpFile, $fileObject, $this->getFolderName());
} catch (Exception $e) {
// we shouldn't get an error here, but just in case
$error = $e->getMessage();
return null;
}
// Check if upload field has an error
if ($this->upload->isError()) {
$error = implode(' ' . PHP_EOL, $this->upload->getErrors());
return null;
}
// return file
return $this->upload->getFile();
}
}
Thanks #3dgoo to give me a part of the solution!
I don't now about a API but with some code I was able to do that.
You have two possibilities.
First using database.
Second using only code:
$directory = '/teste/www/fotos/';
$files = glob($directory . '*.jpg');
if ( $files !== false )
{
$filecount = count( $files );
$newid = $filecount+1;
$new_name = "foto_".$newid;
$target_file = $directory."/".$new_name;
move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $target_file);
}
else
{
$new_name = "foto_1";
$target_file = $directory."/".$new_name;
move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $target_file);
}
My example is for jpeg but you can look for hall types.
I am trying to figure out a way of searching through all of the *.php files inside the parent directory, parent directory example:
/content/themes/default/
I am not wanting to search through all of the files in the sub-directories. I am wanting to search for a string embedded in the PHP comment syntax, such as:
/* Name: default */
If the variable is found, then get the file name and/or path. I have tried googling this, and thinking of custom ways to do it, this is what I have attempted so far:
public function build_active_theme() {
$dir = CONTENT_DIR . 'themes/' . $this->get_active_theme() . '/';
$theme_files = array();
foreach(glob($dir . '*.php') as $file) {
$theme_files[] = $file;
}
$count = null;
foreach($theme_files as $file) {
$file_contents = file_get_contents($file);
$count++;
if(strpos($file_contents, 'Main')) {
$array_pos = $count;
$main_file = $theme_files[$array_pos];
echo $main_file;
}
}
}
So as you can see I added all the found files into an array, then got the content of each file, and search through it looking for the variable 'Main', if the variable was found, get the current auto-incremented number, and get the path from the array, however it was always telling me the wrong file, which had nothing close to 'Main'.
I believe CMS's such as Wordpress use a similar feature for plugin development, where it searches through all the files for the correct plugin details (which is what I want to make, but for themes).
Thanks,
Kieron
Like David said in his comment arrays are zero indexed in php. $count is being incremented ($count++) before being used as the index for $theme_files. Move $count++ to the end of the loop, And it will be incremented after the index look up.
public function build_active_theme() {
$dir = CONTENT_DIR . 'themes/' . $this->get_active_theme() . '/';
$theme_files = array();
foreach(glob($dir . '*.php') as $file) {
$theme_files[] = $file;
}
$count = null;
foreach($theme_files as $file) {
$file_contents = file_get_contents($file);
if(strpos($file_contents, 'Main')) {
$array_pos = $count;
$main_file = $theme_files[$array_pos];
echo $main_file;
}
$count++;
}
}
I have searched the forum but the closest question which is about the control stream did not help or I did not understand so I want to ask a different question.
I have an html form which uploads multiples files to a directory. The upload manager that handles the upload resides in the same script with a different code which I need to pass the file names to for processing.
The problem is that the files get uploaded but they don't get processed by the the other code. I am not sure about the right way to pass the $_FILES['uploadedFile']['tmp_name']) in the adjoining code so the files can be processed with the remaining code. Please find below the script.
More specif explanation:
this script does specifically 2 things. the first part handles file uploads and the second part starting from the italised comment extracts data from the numerous uploaded files. This part has a variable $_infile which is array which is suppose to get the uploaded files. I need to pass the files into this array. so far I struggled and did this: $inFiles = ($_FILES['uploadedFile']['tmp_name']); which is not working. You can see it also in the full code sample below. there is no error but the files are not passed and they are not processed after uploading.
<?php
// This part uploads text files
if (isset($_POST['uploadfiles'])) {
if (isset($_POST['uploadfiles'])) {
$number_of_uploaded_files = 0;
$number_of_moved_files = 0;
$uploaded_files = array();
$upload_directory = dirname(__file__) . '/Uploads/';
for ($i = 0; $i < count($_FILES['uploadedFile']['name']); $i++) {
//$number_of_file_fields++;
if ($_FILES['uploadedFile']['name'][$i] != '') { //check if file field empty or not
$number_of_uploaded_files++;
$uploaded_files[] = $_FILES['uploadedFile']['name'][$i];
//if (is_uploaded_file($_FILES['uploadedFile']['name'])){
if (move_uploaded_file($_FILES['uploadedFile']['tmp_name'][$i], $upload_directory . $_FILES['uploadedFile']['name'][$i])) {
$number_of_moved_files++;
}
}
}
}
echo "Files successfully uploaded . <br/>" ;
echo "Number of files submitted $number_of_uploaded_files . <br/>";
echo "Number of successfully moved files $number_of_moved_files . <br/>";
echo "File Names are <br/>" . implode(',', $uploaded_files);
*/* This is the start of a script to accept the uploaded into another array of it own for* processing.*/
$searchCriteria = array('$GPRMC');
//creating a reference for multiple text files in an array
**$inFiles = ($_FILES['uploadedFile']['tmp_name']);**
$outFile = fopen("outputRMC.txt", "w");
$outFile2 = fopen("outputGGA.txt", "w");
//processing individual files in the array called $inFiles via foreach loop
if (is_array($inFiles)) {
foreach($inFiles as $inFileName) {
$numLines = 1;
//opening the input file
$inFiles = fopen($inFileName,"r");
//This line below initially was used to obtain the the output of each textfile processed.
//dirname($inFileName).basename($inFileName,'.txt').'_out.txt',"w");
//reading the inFile line by line and outputting the line if searchCriteria is met
while(!feof($inFiles)) {
$line = fgets($inFiles);
$lineTokens = explode(',',$line);
if(in_array($lineTokens[0],$searchCriteria)) {
if (fwrite($outFile,$line)===FALSE){
echo "Problem w*riting to file\n";
}
$numLines++;
}
// Defining search criteria for $GPGGA
$lineTokens = explode(',',$line);
$searchCriteria2 = array('$GPGGA');
if(in_array($lineTokens[0],$searchCriteria2)) {
if (fwrite($outFile2,$line)===FALSE){
echo "Problem writing to file\n";
}
}
}
}
echo "<p>For the file ".$inFileName." read ".$numLines;
//close the in files
fclose($_FILES['uploadedFile']['tmp_name']);
fflush($outFile);
fflush($outFile2);
}
fclose($outFile);
fclose($outFile2);
}

Try this upload class instead and see if it helps:
To use it simply Upload::files('/to/this/directory/');
It returns an array of file names that where uploaded. (it may rename the file if it already exists in the upload directory)
class Upload {
public static function file($file, $directory) {
if (!is_dir($directory)) {
if (!#mkdir($directory)) {
throw new Exception('Upload directory does not exists and could not be created');
}
if (!#chmod($directory, 0777)) {
throw new Exception('Could not modify upload directory permissions');
}
}
if ($file['error'] != 0) {
throw new Exception('Error uploading file: '.$file['error']);
}
$file_name = $directory.$file['name'];
$i = 2;
while (file_exists($file_name)) {
$parts = explode('.', $file['name']);
$parts[0] .= '('.$i.')';
$new_file_name = $directory.implode('.', $parts);
if (!file_exists($new_file_name)) {
$file_name = $new_file_name;
}
$i++;
}
if (!#move_uploaded_file($file['tmp_name'], $file_name)) {
throw new Exception('Could not move uploaded file ('.$file['tmp_name'].') to: '.$file_name);
}
if (!#chmod($file_name, 0777)) {
throw new Exception('Could not modify uploaded file ('.$file_name.') permissions');
}
return $file_name;
}
public static function files($directory) {
if (sizeof($_FILES) > 0) {
$uploads = array();
foreach ($_FILES as $file) {
if (!is_uploaded_file($file['tmp_name'])) {
continue;
}
$file_name = static::file($file, $directory);
array_push($uploads, $file_name);
}
return $uploads;
}
return null;
}
}
hy, i need a little help here:
i use SWFupload to upload images!
in the upload function i make a folder call $_SESSION['folder'] and all the files i upload are in 1 array call $_SESSION['files'] after uploads finish i print_r($_SESSION) but the array is empty? why that?
this is my upload.php:
if($_FILES['image']['name']) {
list($name,$error) = upload('image','jpeg,jpg,png');
if($error) {$result = $error;}
if($name) { // Upload Successful
$result = watermark($name);
print '<img src="uploads/'.$_SESSION['dir'].'/'.$result.'" />';
} else { // Upload failed for some reason.
print 'noname'.$result;
}
}
function upload($file_id, $types="") {
if(!$_FILES[$file_id]['name']) return array('','No file specified');
$isimage = #getimagesize($_FILES[$file_id]['tmp_name']);
if (!$isimage)return array('','Not jpg');
$file_title = $_FILES[$file_id]['name'];
//Get file extension
$ext_arr = split("\.",basename($file_title));
$ext = strtolower($ext_arr[count($ext_arr)-1]); //Get the last extension
//Not really uniqe - but for all practical reasons, it is
$uniqer = substr(md5(uniqid(rand(),1)),0,10);
//$file_name = $uniqer . '_' . $file_title;//Get Unique Name
//$file_name = $file_title;
$file_name = $uniqer.".".$ext;
$all_types = explode(",",strtolower($types));
if($types) {
if(in_array($ext,$all_types));
else {
$result = "'".$_FILES[$file_id]['name']."' is not a valid file."; //Show error if any.
return array('',$result);
}
}
if((!isset($_SESSION['dir'])) || (!file_exists('uploads/'.$_SESSION['dir']))){
$dirname = date("YmdHis"); // 20010310143223
$pathtodir = $_SERVER['DOCUMENT_ROOT']."/ifunk/uploads/";
$newdir = $pathtodir.$dirname;
if(!mkdir($newdir, 0777)){return array('','cannot create directory');}
$_SESSION['dir'] = $dirname;
}
if(!isset($_SESSION['files'])){$_SESSION['files'] = array();}
//Where the file must be uploaded to
$folder = 'uploads/'.$_SESSION['dir'].'/';
//if($folder) $folder .= '/'; //Add a '/' at the end of the folder
$uploadfile = $folder.$file_name;
$result = '';
//Move the file from the stored location to the new location
if (!move_uploaded_file($_FILES[$file_id]['tmp_name'], $uploadfile)) {
$result = "Cannot upload the file '".$_FILES[$file_id]['name']."'"; //Show error if any.
if(!file_exists($folder)) {
$result .= " : Folder don't exist.";
} elseif(!is_writable($folder)) {
$result .= " : Folder not writable.";
} elseif(!is_writable($uploadfile)) {
$result .= " : File not writable.";
}
$file_name = '';
} else {
if(!$_FILES[$file_id]['size']) { //Check if the file is made
#unlink($uploadfile);//Delete the Empty file
$file_name = '';
$result = "Empty file found - please use a valid file."; //Show the error message
} else {
//$_SESSION['files'] = array();
$_SESSION['files'][] .= $file_name;
chmod($uploadfile,0777);//Make it universally writable.
}
}
return array($file_name,$result);
}
SWFUpload doesn't pass the session ID to the script when you upload, so you have to do this yourself. Simply pass the session ID in a get or post param to the upload script, and then in your application do this before session_start:
if(isset($_REQUEST['PHPSESSID'])) {
session_id($_REQUEST['PHPSESSID']);
}
you must pass the session ID to the upload file used by swfupload.
