Highlight search text in embedded pdf

[Sally]

Hi,

I am using PdfEmbed to display pdf files. Is there a way to highlight search text in the pdf document itself without using the "find tool" in the pdf viewer? Basically I want to pass the search term from the URL query and highlight all matches in the pdf document.

Thanks,

I was looking into this issue a while ago, and at that time it was not possible due to security restrictions of PDF.js preventing search terms to be directly passed to the script.

However, that was some time ago, and at least according to this thread things have changed - https://github.com/mozilla/pdf.js/issues/1875. Looks like you can pass the search parameters in the URL via GET, and modify viewer.js with the sample code towards the bottom of the page in order to parse them correctly.

If you decide to try it out, let me know how it works.

Thanks for link, Anurag.

 Actually, the feature is already implemented in the latest version of Pdf.js (1.4.20). I updated the pdf.js library to v.1.4.20 in PdfEmbed plugin. Yes, it works! Just need to append search param to src file path in PdfEmbedPlugin.php, function embedPdfJs($file, $options):

$query = htmlspecialchars($_GET["query"]);
$attrs['src'] = $pdfJsViewer
            . '?file=' . rawurlencode($file->getWebPath('original'))
            . $hash . '#zoom=100&' . 'search=' . $query;

Oh, excellent! Thanks for the update - I'll have to give it a try.
