Squeeze Form – Downloading PDF result of Zero Bytes

[ohwowmarketing]

I saw one of the topic here, but still give it a try. At first we were excited. But after the plugin was deploy to the live site, customers who tried to download the PDF ends with Zero Bytes.

I tried to debug but no luck.
I tried also to follow your suggestion about PHP Dispatch and toggle the check box for luck, still no works.

I tried to install new fresh wordpress on my Mamp and install all your plugins, and guess what… still Zero bytes for the pdf file.

Have you tried to check it lately guys if this still working? I mean, paying you almost $30 seems not worth for this plugin…

Let me look into this. Are you using the secure downloads addon or just the main plugin? If you are using the secure download addon then are you using the dropbox option or just uploading the PDF file directly to your site?

Can you share a link to the page where I can go and inspect the download button?

Regarding page, I will create one for you guys.

The sample page you showed looks very strange. It doesn’t have any header or footer. This plugin outputs some JavaScript code in the header. If the header is not loaded then it may not work correctly. Can you use a standard default WordPress theme (some like the twenty seventeen theme from wordpress) then use the shortcode on a page and see if you see the same behavior?

As your suggestion, please watch the video. drive.google.com/open?id=1VBzlkoUtNUASF9mSIHmr5Pz-83fVD_rK

Actually, my theme does heave header and footer. Since it was custom theme (and fresh installed) made by me to my client, it was more optimized than the usual.

Thank you. Your setup looks fine to me. PHP must be failing to dispatch the correct header on this site for some reason. I will take a look inside your site. Please use the contact form on the site to send me access to the site (if possible). It should help me troubleshoot this.

Hello.

It’s been 4 and half months after I open this thread. My bad I didn’t provide yet any access to the author. However, it is bad as well that I didn’t see if they’ve manage to check this error/issue.

Anyway, upon debugging “in my case” today April 12, readfile() is failing to give a 200 ok code to the header in-which resulting http/1.1 403 forbidden to the attached PDF file.

`
Warning: readfile(http://localhost:8888/wp-content/uploads/2019/01/Brochure.pdf): failed to open stream: HTTP request failed! HTTP/1.1 403 Forbidden in /Users/mac/Sites/sandbox/wp-content/plugins/sdm-squeeze-form/sdm-sf-shortcodes.php on line 281
`

Base on my findings, readfile() throwing 403 to the pdf attachment which ending-up zero-byte. I tried to create small code inside the sdm-sf-shortcodes.php

`
$parsed = parse_url( get_post_meta($postid, ‘sdm_upload’, true) );
$url = dirname( $parsed [ ‘path’ ] ) . ‘/’ . rawurlencode( basename( $parsed[ ‘path’ ] ) );

$filePath = ABSPATH . substr($url, 1);
`

then I rewrite the readfile( $file ) var into readfile( $filePath );

Overall, I am still open for some comments if they’ve manage to fix this issue. Else, i will mark this as resolved, if I can prove that the code I am using is the solution to this case.

Regards,

This one is a site specific issue. If the code that you are using now is working then that’s totally fine.

ok, so this is the final code that is completely working.

$parsed = parse_url( get_post_meta($postid, 'sdm_upload', true) );
$url    = dirname( $parsed [ 'path' ] ) . '/' . rawurlencode( basename( $parsed[ 'path' ] ) );

// Combine the absolute path and the attachment url
$filePath = ABSPATH . substr($url, 1);

// Get the attachment file-size
$size = filesize($filePath);

// Temporary disable due to error
// $headers = get_headers($file, 1);
// $fsize = $headers['Content-Length'];

here’s the code will look like after the provision codes.

header('Content-Length: ' . $size);
readfile( $filePath );

Hope this will help others.
