I have many documents on my server that are available for my visitors to download. I have a display set up like so:
<ul class="thumbnails">
<li class="span4">
<div class="thumbnail">
<img src="http://placehold.it/320X200" alt="ALT NAME">
<div class="caption">
<h3>Header Name</h3>
<p>Description</p>
<p align="center">Download</p>
</div>
</div>
</li>
</ul>
Now within this I currently have a image as the main display for each document. I am wanting to display a preview of the document in that space. Maybe a screenshot completed by the browser on page load of just the first page of the document.
I have tried <iframe src="assets/documents/NHSHandbook1314.doc" width="230" height="144"></iframe> instead of the image but that resulted in nothing being displayed in the iframe and the document downloading as soon as the page loads.
I would like to do this using javascript or php on page load. I basically want the browser to take a "screenshot" of the external document and then display it for the visitor to preview. I don't want them to be able to interact "read" the document from the preview, just see what they are downloading. (at least the first page)
I hope that makes sense on what I am wanting to do!
Browsers cannot render Microsoft Word documents. You will need to generate some sort of thumbnail on the server and display that.

How do I format a link that will go to an anchor within a PHP document?
For example:
http://chambervu.com/lososos/index.php#p=10 - does not display the intended result, however if I go to http://chambervu.com/lososos/index.php then once that page is displayed if I append "#p=10" then everything displays as intended. How would I form the link to display page 10 directly?
The "pages" in my index file are setup like this:
<li class="page" data-name="5">
<div class="blah....blah"
</div>
</li>
</div>
</li>
<li class="page" data-name="6">
<div class="blah..blah"
</div>
</li>
Fragments point to an ID on the page, when you visit an HTML page with a fragment in the URL, the browser tries to find an element with a matching ID and scroll to it.
The javascript you have running on the page takes the fragment when it changes (after the page has loaded) and parses it to determine which page to show.
Linking directly to that page like you want would require some editting of the javascript at the very least.
In my project's homepage there must be some images, these must link to other pages. Now, I want to manage these links in an automatic way using PHP. The only idea I came up with is to make a form and insert the images into some buttons and make their background invisible.
<div class="container">
<div class="row">
<div class="col-md-4">
<h3>FRESH ALBUMS</h3>
</div>
</div>
<div id="myline"></div>
<div class="row">
<div class="col-md-3">
<img src="contentimg/abbeyroad.jpg" height="200px" width="200px">
<div class="caption">
<h4>Beatles</h4>
</div>
<p> test</p>
</div>
<div class="col-md-3">TEST2</div>
<div class="col-md-3">TEST3</div>
<div class="col-md-3">TEST4</div>
</div>
</div>
This is the HTML at the moment. I just want to know if there are better ideas, options and if it will stay responsive. Thanks in advance.
I do not understand exactly what you are asking, but I cannot leave comments so I will try to answer what I think you are asking.
For the HTML part, you don't need a form with buttons, you can make hyperlinks out of the images instead, and the PHP can get the images to match the hyperlinks when it sends the page to your users browser. The PHP code would look like:
echo "
<a href='".$newPageLink."'>
<img src='".$imageLocation."' width='100px' height='100px'>
</a>";
Where $newPageLink is a variable in your PHP script that holds the path information for your hyperlink, and $imageLocation is the path information for where the image is stored.
All you need is a foreach or while loop to go through all of the images that you want on the page and also all of the pages that each image should link to. If it is always a manageable and unchanging list, you could store the values in an array in your script. For larger lists, or lists that are dynamic/always changing you might need to use a MySQL database table to store the image and hyperlink information.
So I've got a part on my website where I show a pdf in an iframe.
This works perfectly fine on computers.
However, some mobile devices start downloading the pdf immediately when they load the website.
This is the code I use.
<div class="showbox" style="display: none;">
<div class="embed-container">
<iframe src="/images/pdf-file.pdf" style="border:none;"></iframe>
</div>
</div>
So I just want the mobile users to be able to visit the website without automatically downloading the pdf.
Any ideas how to pull this off?
how about you use Responsive utility classes ?
take a look at: http://getbootstrap.com/2.3.2/scaffolding.html#responsive
scroll down untill "Responsive utility classes"
you can set your html like this:
<div class="showbox" style="display: none;">
<div class="embed-container">
</div>
</div>
and then put this js anywhere:
if( !/Android|webOS|iPhone|iPad|iPod|BlackBerry|IEMobile|Opera Mini/i.test(navigator.userAgent) ) {
$('.showbox .embed-container').append('<iframe src="/images/pdf-file.pdf" style="border:none;"></iframe>');
}
I am using a script, blazy, to change my page's images as the user scrolls down. It works fine, and I would like the user to have the possibility to share each image to his friends on Facebook. I managed to link the url to an anchor to the image. When sharing a link, a little thumbnail is displayed with the link with a short description of the image. My problem is that only the logo of my website is displayed and not the image the user wants to share.
<a class="facebook_share" href="actualites.php#237" onclick="
window.open(
'https://www.facebook.com/sharer/sharer.php?u='+encodeURIComponent(location.href.split(location.hash||'#')[0] + '#237'),
'facebook-share-dialog',
'width=626,height=436');
return false;">
</a>
<div id="237">
<a href="content/posts/237/449.jpg" title="Voir en taille réelle">
<img class="b-lazy"
src="data:image/gif;base64,R0lGODlhAQABAAAAACH5BAEKAAEALAAAAAABAAEAAAICTAEAOw=="
data-src="content/posts/237/449_thumb.png" alt="image" width="700px">
</a>
</div>
Looking at The Open Graph protocol, I tried to create a meta tag when clicking on the Facebook share button. The result is the same -- the image I want to share is not displayed, this is because Facebook linter only looks at the HTML in the response and does not run any scripts. The content of my page always changes, I cannot write the meta tags "by hand".
<a class="facebook_share" href="actualites.php#237" onclick="
$('meta[name=og:image]').remove();
$('head').append('<meta name=\'og:image\' content=\'***/content/posts/237/449_thumb.png\'>');
window.open(...[see above]);
I'm rather new to programming, but I'm trying to find a way to do what is described below.
<body>
<div class="gallery">
<img src="photo_1.jpg">
<img src="photo_2.jpg">
<img src="photo_3.jpg">
<!-- trigger for user to load items that weren't downloaded on page load -->
<img src="photo_4.jpg">
<img src="photo_5.jpg">
<img src="photo_6.jpg">
</div>
</body>
I'm trying to find PHP functions that would, ideally, only load the first 3 img embeds within a certain class/ID, and have a clickable trigger to request the remaining img embeds from the server.
I don't know if this is how the typical message board software(such as vBulletin) handles things with "spoiler tags" .. as in whether or not it actually prevents loading, or just hides the content from view. Something like that, if it actually prevents loading, is what I'd like to know about.
First, this has nothing to do with PHP.
The only way to prevent a page from loading the image is to not include the tags on the page.
You could accomplish this a couple ways:
Place the last three photos inside a hidden container and use a Javascript click event to display them when wanted, but that still loads the images when the page is loaded.
Or, you can use an AJAX call to retrieve the items only on demand. Unless they are really large images I would think the first option the best.
<div class="gallery">
<img src='photo1.jpg'/>
<img src='photo2.jpg'/>
<img src='photo3.jpg'/>
<a href="#" onClick='document.getElementById("hidden-gallery").display="visible"'>show more</a>
<div id="hidden-gallery" class="hidden-gallery" style="display:none">
<img src='photo4.jpg'/>
<img src='photo5.jpg'/>
<img src='photo6.jpg'/>
</div>
</div>
I recognize that embedding CSS styles and Javascript the way I did is not the preferred method but it is there just for the examples sake.
