Remote SVG via cURL Fed to ImageSVG Not Working

[Michael]

Hi, I'm trying to load a few SVGs remotely and feed them into my PDF. I know the .svg files are loading correctly because if I print the cURL result I see them and when I copy/paste the <svg> code directly it works. However, when I try to load via cURL and then feed to ImageSVG I get the following error:
TCPDF ERROR: SVG file not found: @

Here's the code I'm using:

1 2 3 4 5 6

$ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_HEADER, 0); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); $svg_data = curl_exec($ch); $pdf->ImageSVG($file = '@'.$svg_data, $x=15, $y=30, $w='', $h='');

Thanks so much for any help!

Does it work with file_get_contents() rather than curl?

Do you need it to keep a cookie jar to work?

[Michael]

Hmm, no dice with file_get_contents, same error. I don't think I need any kind of cookies because if instead of calling ImageSVG on the last line I do something like print_r($svg_data) the SVG files show in the browser i.e. their data is output correctly.

Is it a public url I can try?

[Michael]

Certainly: http://commons.wikimedia.org/wiki/SVG_examples#mediaviewer/File:SVG_example7.svg

Thanks again for the help

Hmm. Don't know what to say. It worked for me using file_get_contents.

Turns out you're right, it works with cURL too, it was a silly error I hadn't noticed but you telling me it does indeed work helped me figure it out.

Thanks for your help!
