I need to push the image into a folder, here image will generated in for loop according to my query, for each and every loop in need push the $img to a specific folder.
If it's possible..? Kindly give some solution.
<?php
for($i=0;$i<10;$i++)
{
$sql_sub = select_query("select DESPHOT from photo where photoid = ".$i."");
$img = $sql_sub[0][0]->load();
header("Content-type: image/pjpeg");
echo $img;
}
?>
You needs to use file_put_contents function for it.
Try
<?php
for($i=0;$i<10;$i++)
{
$sql_sub = select_query("select DESPHOT from photo where photoid = ".$i."");
$img = $sql_sub[0][0]->load();
$target_folder = 'test';
$filename = $i.'.jpg';
$new_saved = file_put_contents($target_folder.'/'.$filename, $img);
echo "Picture save as ".$new_saved;
}
?>
Note You have to set 0777 permission to target_folder if you are using UNIX/LINUX.
Above code is not tested. What $sql_sub[0][0]->load(); do?
Your going to need move_uploaded_file($tmp_path, $newpath)

There's this code which I have
function pushfile(&$file) {
header_remove();
if (isset($file["type"])) header('Content-Type: '.$file["type"]);
if (isset($file["name"])) header('Content-Disposition: attachment; filename="'.$file["name"].'"');
print $file["name"];
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Pragma: ");
echo $file["content"];
exit;
$h=fopen($filename,"r");
$content = fread($h, filesize($filename));
fclose($h);
$file["type"] = "application/"; //
$file["name"] = $real_filename;
$file["content"] = $content."*".$context['user']['id'];
pushfile($file);
This ID number was well placed into the downloaded file, but it disappeared after converting it (e.g. from pdf to epub). Is there a good solution for that?
I am having difficulty working out my download.php script. The customer gets a unique download link generated from my database and when they click it on it is meant to send them the file from my server. Only in my case the zip file is always corrupt and bigger then the original file. Original file is 68KB and the downloaded file ends up being 90KB.
Here is my code that sends the file to the browser:
<?php
$actual_link = "http://$_SERVER[HTTP_HOST]";
$post_id = $wpdb->get_results("SELECT transaction_id FROM slx_jomsocial_plugin_orders WHERE (transaction_id ='". $tx ."' and unique_code='". $token ."')");
$rowCount = $wpdb->num_rows;
if($rowCount==1){
$name="Unzip_First_Video_Embedding.zip";
$file_url=$actual_link."/jomsplugins/".$name;
header("Content-type: application/x-file-to-save");
header("Content-Disposition: attachment; filename=".$name);
readfile($file_url);
echo "<h1>Thank you ".$name=$_SESSION['s_name']." For downloading the plugins.</h1><br />";
}else{
echo "<h1>You are not permitted to downlaod, Please purchase plugin first.</h1> <br /><div style=\"margin-left: 25%;margin-top: 1%;\">Click Here</div>";
}
?>
What am I doing wrong here?
UPDATE:
I have been experimenting with the script but still my files come out corrupted (Unzipping them gives a .cpgz file). Here is my current script now:
<?php
$actual_link = "http://$_SERVER[HTTP_HOST]";
$post_id = $wpdb->get_results("SELECT transaction_id FROM slx_jomsocial_plugin_orders WHERE (transaction_id ='". $tx ."' and unique_code='". $token ."')");
$rowCount = $wpdb->num_rows;
if($rowCount==1){
// set example variables
$filename = "Unzip_First_Video_Embedding.zip";
$filepath = $actual_link."/jomsplugins/";
// http headers for zip downloads
header("Pragma: public");
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Cache-Control: public");
header("Content-Description: File Transfer");
header("Content-type: application/octet-stream");
header("Content-Disposition: attachment; filename=\"".$filename."\"");
header("Content-Transfer-Encoding: binary");
ob_end_flush();
ob_clean();
flush();
#readfile($filepath.$filename);
ob_clean();
flush();
exit;
}
So what I am trying to do is take 2 strings and create 2 files. Then create a zip out of these files and let a user download them.
Here is what I have:
$string1 = 'Some data some data some data';
$string2 = 'Some data some data some data';
$zip = new ZipArchive();
$filename = "test.zip";
if ($zip->open($filename, ZIPARCHIVE::CREATE)!==TRUE) {
exit("cannot open <$filename>\n");
}
$zip->addFromString("string1.txt", $string1);
$zip->addFromString("string2.txt", $string2);
$zip->close();
header("Pragma: public");
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Cache-Control: public");
header("Content-Description: File Transfer");
header("Content-type: application/octet-stream");
header("Content-Disposition: attachment; filename=\"".$filename."\"");
header("Content-Transfer-Encoding: binary");
header("Content-Length: ".filesize('test.zip'));
So far no luck. Any help is appreciated.
You missed the most important part - output the file! :)
Add:
readfile('test.zip');
to the end of the php file.
Also the calculation of the HTTP content-length header is wrong:
header("Content-Length: ".filesize($zip));
This will give you always 0 ( or false) as filesize expects a filename as its argument.
Change the line to:
header("Content-Length: ".filesize('test.zip'));
After doing both of this the zip will successfully download and contains the two files. For completenes, here comes the full working example:
$string1 = 'Some data some data some data';
$string2 = 'Some data some data some data';
$zip = new ZipArchive();
$filename = "test.zip";
if ($zip->open($filename, ZIPARCHIVE::CREATE)!==TRUE) {
exit("cannot open <$filename>\n");
}
$zip->addFromString("string1.txt", $string1);
$zip->addFromString("string2.txt", $string1);
$zip->close();
header("Pragma: public");
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Cache-Control: public");
header("Content-Description: File Transfer");
header("Content-type: application/octet-stream");
header("Content-Disposition: attachment; filename=\"".$filename."\"");
header("Content-Transfer-Encoding: binary");
// make sure the file size isn't cached
clearstatcache();
header("Content-Length: ".filesize('test.zip'));
// output the file
readfile('test.zip');
You have a PHP error (you probably dont have error reporting turned on or high enough error level).
the filesize() function takes a string not an object. filesize($filename) will work.
to turn on error reporting do:
error_reporting(E_ALL|E_STRICT);
ini_set('display_errors', 1);
alternatively do this in php.ini
After all those header() calls, I think you want:
readfile($filename);
I want to read an excel file with php and send its content to the client. What I really want to do is by changing the content type and other html headers force browser to download the file instead of showing its content. Everything is ok and user can download the file but when he tries to open it contents are not displayed in right format and shape. The thing which comes to my mind is that I should not send response in unicode string and have to do it in binary format which excel can know it. This is my current code :
$filename = $_GET['file'];
$ext = $_GET['type'];
$filename .= '.' . $ext;
$path = "../generatedReports/" . $filename;
header('Content-type: application/vnd.ms-excel;');
header('Content-Disposition: attachment; filename=' . $filename);
header("Pragma: public");
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Cache-Control: public", false);
header("Content-Description: File Transfer");
header("Accept-Ranges: bytes");
header("Content-Transfer-Encoding: binary");
header("Content-Length: " . filesize($path));
$size = filesize($path);
$f = fopen($path, 'r');
$content = fread($f, $size);
echo $content;
Any solution?
Please try with the below code,
echo unicode2utf8(hexdec("00CE")); // Result: Î
// Or the function that will recognize U+ in front of string, and will skip it to show the character
function unicodeCodePointToChar($str) {
if (substr($str,0,2) != "U+") return $str;
$str = substr($str,2); // Skip U+
return unicode_to_utf8(array(hexdec($str)));
}
echo unicodeCodePointToChar("U+00CE"); // Result: Î
my problem was solved by this answer. I've changed my code to this :
$filename = $_GET['file'];
$ext = $_GET['type'];
$filename .= '.' . $ext;
$path = "../generatedReports/" . $filename;
header('Content-type: application/vnd.ms-excel;');
header('Content-Disposition: attachment; filename=' . $filename);
header("Pragma: public");
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Cache-Control: public", false);
header("Content-Description: File Transfer");
header("Accept-Ranges: bytes");
header("Content-Transfer-Encoding: binary");
ob_clean(); // discard any data in the output buffer (if possible)
flush(); // flush headers (if pos
readfile($path);
and everything got nice.
I have Excel spreadsheets stored in a MySQL table longblob field. I need to retrieve this data and then stream it to the user as a downloadable file, preferably without writing it to disk first.
Possible?
Edit - Eh, just figured it out... Posted in answer below.
function getfile($blockid)
{
global $msa_db;
$sql = "select filename, filedata from blocks where blockid = '$blockid'";
$query = mysql_query($sql, $msa_db);
$result['filename'] = mysql_result($query,0,0);
$result['filedata'] = mysql_result($query,0,1);
return $result;
}
function download($fileinfo)
{
$file = base64_decode($fileinfo['filedata']);
header("Cache-Control: no-cache private");
header("Content-Description: File Transfer");
header('Content-disposition: attachment; filename='.$fileinfo['filename']);
header("Content-Type: application/vnd.ms-excel");
header("Content-Transfer-Encoding: binary");
header('Content-Length: '. strlen($file));
echo $file;
exit;
}
$fileinfo = getfile($blockid);
download($fileinfo);
Just got the solution
http://www.codeproject.com/Articles/831185/CREATE-DOWNLOAD-ZIP-FILE-USING-PHP
$data = base64_decode($data);
header("Cache-Control: no-cache private");
header("Content-Description: File Transfer");
header("Content-disposition: attachment; filename='".$identifier.".zip'");
header("Content-Type: application/octet-stream");
header("Content-Transfer-Encoding: binary");
header('Content-Length: '. strlen($data));
header("Pragma: no-cache");
header("Expires: 0");
ob_clean();
flush();
echo $data;
