I'm trying to write an Joomla plugin to add width and height tag to each <img>
in HTML file. Some image file names are Persian, and getimagesize faces error.
The code is this:
@$dom->loadHTML('<?xml version="1.0" encoding="UTF-8"?>' . "\n" . '
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
</head>
<body>
<img src="images\banners\س.jpg" style="max-width: 90%;" >
</body>
</html>
');
$x = new DOMXPath($dom);
foreach($x->query("//img") as $node)
{
$imgtag = $node->getAttribute("src");
$imgtag = pathinfo($imgtag);
$imgtag = $imgtag['dirname'].'\\'.$imgtag['basename'];
$imgtag = getimagesize($imgtag);
$node->setAttribute("width",$imgtag[0]);
$node->setAttribute("height",$imgtag[1]);
}
$newHtml = urldecode($dom->saveHtml($dom->documentElement));
And when Persian characters exist in file name, getimagesize shows:
Warning: getimagesize(images\\banners\\س.jpg): failed to open stream: No such file or directory in C:\\wamp64\\www\\plugin.php
How can I solve this?
Thanks to all, I couldn't reach to results on WAMP server (local server on Windows), but when I migrated to Linux server, finally this code worked properly.
$html = $app->getBody();
setlocale(LC_ALL, '');
$dom = new DOMDocument();
@$dom->loadHTML($html);
$x = new DOMXPath($dom);
foreach($x->query("//img") as $node)
{
$imgtag = $node->getAttribute("src");
if(strpos($imgtag,"data:image")===false)
{
$imgtag = getimagesize($imgtag);
$node->setAttribute("width",$imgtag[0]);
$node->setAttribute("height",$imgtag[1]);
}
}
$bodytag = $x->query("//body");
$node = $dom->createElement("script", ' /* java script which may be necessary on client */ ');
$bodytag[0]->appendChild($node);
$html = '<!DOCTYPE html>'."\n" . $dom->saveHtml($dom->documentElement);
Some hints:
<!DOCTYPE html>
should be added to final DOM object output :)
