Upload a servidor FTP de varios archivos con AJAX Les muestro los ejemplos:
http://the-stickman.com/web-developm...-file-element/
http://www.seemysites.net/projFolder/uploader/
El primero lo hice de esta forma:
Todo va dentro del upload.php
Código PHP:
<?
$rpta = "";
if ($_POST["action"] == "upload") {
$tmpfile = $_FILES['file_1']['tmp_name'];
$tmpname = $_FILES['file_1']['name'];
$ftpuser = "miusuario";
$ftppass = "mipassword";
$ftppath = "ftp.miservidor.com.ar/public_html/fotos/";
$ftpurl = "ftp://".$ftpuser.":".$ftppass."@".$ftppath;
if ($tmpname != "") {
$fp = fopen($tmpfile, 'r');
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $ftpurl.$tmpname);
curl_setopt($ch, CURLOPT_UPLOAD, 2);
curl_setopt($ch, CURLOPT_INFILE, $fp);
curl_setopt($ch, CURLOPT_INFILESIZE, filesize($tmpfile));
curl_exec($ch);
$error = curl_errno($ch);
curl_close ($ch);
if ($error == 0) {
$rpta = 'Archivo subido correctamente.';
} else {
$rpta = 'Error al subir el archivo.';
}
} else {
$rpta = 'Seleccionar un archivo.';
}
}
?> Código HTML:
<head> <!-- Include the javascript --> <script src="multifile_compressed.js"></script> </head> <body> <!-- This is the form --> <form enctype="multipart/form-data" action="upload.php" method = "post"> <!-- The file element -- NOTE: it has an ID --> <input id="my_file_element" type="file" name="file_1" > <input type="submit"> <input type="hidden" name="action" value="upload" /> </form> Files: <!-- This is where the output will appear --> <div id="files_list"></div> <script> <!-- Create an instance of the multiSelector class, pass it the output target and the max number of files --> var multi_selector = new MultiSelector( document.getElementById( 'files_list' ), 3 ); <!-- Pass in the file element --> multi_selector.addElement( document.getElementById( 'my_file_element' ) ); </script> </body>
Código HTML:
function MultiSelector( list_target, max ){
// Where to write the list
this.list_target = list_target;
// How many elements?
this.count = 0;
// How many elements?
this.id = 0;
// Is there a maximum?
if( max ){
this.max = max;
} else {
this.max = -1;
};
/**
* Add a new file input element
*/
this.addElement = function( element ){
// Make sure it's a file input element
if( element.tagName == 'INPUT' && element.type == 'file' ){
// Element name -- what number am I?
element.name = 'file_' + this.id++;
// Add reference to this object
element.multi_selector = this;
// What to do when a file is selected
element.onchange = function(){
// New file input
var new_element = document.createElement( 'input' );
new_element.type = 'file';
// Add new element
this.parentNode.insertBefore( new_element, this );
// Apply 'update' to element
this.multi_selector.addElement( new_element );
// Update list
this.multi_selector.addListRow( this );
// Hide this: we can't use display:none because Safari doesn't like it
this.style.position = 'absolute';
this.style.left = '-1000px';
};
// If we've reached maximum number, disable input element
if( this.max != -1 && this.count >= this.max ){
element.disabled = true;
};
// File element counter
this.count++;
// Most recent element
this.current_element = element;
} else {
// This can only be applied to file input elements!
alert( 'Error: not a file input element' );
};
};
/**
* Add a new row to the list of files
*/
this.addListRow = function( element ){
// Row div
var new_row = document.createElement( 'div' );
// Delete button
var new_row_button = document.createElement( 'input' );
new_row_button.type = 'button';
new_row_button.value = 'Delete';
// References
new_row.element = element;
// Delete function
new_row_button.onclick= function(){
// Remove element from form
this.parentNode.element.parentNode.removeChild( this.parentNode.element );
// Remove this row from the list
this.parentNode.parentNode.removeChild( this.parentNode );
// Decrement counter
this.parentNode.element.multi_selector.count--;
// Re-enable input element (if it's disabled)
this.parentNode.element.multi_selector.current_element.disabled = false;
// Appease Safari
// without it Safari wants to reload the browser window
// which nixes your already queued uploads
return false;
};
// Set row value
new_row.innerHTML = element.value;
// Add button
new_row.appendChild( new_row_button );
// Add it to the list
this.list_target.appendChild( new_row );
};
};
¿Dónde puede estar el error?
¿Se pueden subir varios archivos a la vez a un servidor?
Muchas gracias de entemano.
Saludos. Marx.
