Insead of having to alter values for every item in the list as so
<li class="item drawing">
<a class="fancybox" rel="group" href="images/portfolio/skateboard_l.jpg">
<img src="images/portfolio/skateboard.jpg" alt="skateboard"/>
<h3>Skateboard</h3>
</a>
</li>
Is it possible to have something like
item="Skateboard
<li class="item drawing">
<a class="fancybox" rel="group" href="images/portfolio/[item-lowercase][if "item"_l.jpg exists, echo"_l"].jpg">
<img src="images/portfolio/[item-lowercase].jpg" alt="[item-lowercase]"/>
<h3>[item]</h3>
</a>
</li>
So I can just change the item variable for each item in the list rather than all the seperate entries. I assume this would be done using PHP or JS?
Thanks.
You want to use templates I guess.
If you want to do it client side in JS:
underscore
Mustache.js
Handlebars.js
The best solution that I can think of is to build an array (I would use PHP)... then use a while loop to build your list... put it all in a function and call it wherever you need it...
For example:
<?php
function itemList(){
$items=array ("skateboard","rollerskates","scooter","rollerblades");
reset($items);
while (list(, $value) = each($items)) {
echo '<li class="item drawing">';
echo '<a class="fancybox" rel="group" href="images/portfolio/' . $value . '_l.jpg">';
echo '<img src="images/portfolio/' . $value . '.jpg" alt="' . $value . '"/>';
echo '<h3>' . $value . '</h3>'; echo '</a>';
echo '</li>';
}
}
?>
Then in your HTML file (where you want the list to be displayed):
<ul><?php itemList(); ?></ul>
If you put the function in a separate .php file, you have to include it in the HTML document:
<?php include ('/url/of/list.php'); ?>
You can do this in PHP using echo.
For instance, if the image name was stored in $images["myImage"] and the alt was $imageAlts["myImage"
<img src="images/portfolio/<?php echo $images["myImage"]; ?>.jpg" alt="<?php echo $imageAlts["myImage"]; ?>"/>
Looks like AngularJS would help as well. It lets you do stuff like this:
<!doctype html>
<html ng-app>
<head>
<script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.0.2/angular.min.js"></script>
</head>
<body>
<div>
<label>Name:</label>
<input type="text" ng-model="yourName" placeholder="Enter a name here">
<hr>
<h1>Hello {{yourName}}!</h1>
</div>
</body>
</html>
Smarty is a good template system for PHP. If you'd like to use PHP for templating over JavaScript, just start with one of the tutorials there (or look into other PHP template systems).
A classic way to do this in PHP would be to create an array of items in PHP and then iterate over the array, creating the HTML list items with the appropriate [item-lowercase] entries.
I would consider doing the [if item exists] as part of the process that builds your data array so you don't have to do anything complicated when you build your html. Then, just loop through your array and display whatever is in $theItem.
This is, of course, a simplification.
foreach($itemList as $key=>$theItem){
?>
<li class="item drawing">
<a class="fancybox" rel="group" href="images/portfolio/<?php echo $theItem ?>
<img src="images/portfolio/[item-lowercase].jpg" alt="[item-lowercase]"/>
<h3>[item]</h3>
</a>
</li>
<?php
}

I have problem looping out pictures from a database.
I have no problem getting the information(string) that I need from the database. The problems accure when I try to use the string as a img src-tag.
My code:
<?php
foreach ($console as $con):
echo '<li>', $con['brand'], ', ',$con['pic'], '</li>';
echo'<div class="item2">
<a href="xboxconsol.html">
<img src=',$con['pic'],'/>
</a>
</div>';
endforeach;
?>
Note, the li-elements put out the correct information but when I use it in the img-tag it adds a "/" at the end on the string.
Example of list output:
Playstation, ../playstation.jpg
The picutre however output the URL to the pic as:
../playstation.jpg/
Where do the last "/" come from and how do I get rid of it?
You need to quote the attribute value.
echo'<div class="item2">
<a href="xboxconsol.html">
<img src="',$con['pic'],'"/>
</a>
</div>';
Currently the browser is guessing what the attribute should contain.
Which comes out as:
<img src="value/">
but you want:
<img src="value"/>
You need to quote your concatenations, be very careful how you output HTML from PHP.
I'd rather concatenate the variables like this instead:
foreach ($console as $con)
{
echo "<li>{$con['brand']} {$con['pic']}</li>";
echo "<div class='item2'>
<a href='xboxconsol.html'>
<img src=\"{$con['pic']}\" />
</a>
</div>";
}
It's way cleaner and more readable.
I wrote a code which is retrive image paths and display on the website in bootstrap grid style.But it does not showing the image. Code is working fine, Please help me. here is my code
<div class="row">
<?while ($row = mysql_fetch_assoc($query)) {?>
<div class = "col-md-3">
<?php echo $row['keywords'];?>
<?php $imagePath = $row['video_url'];?>
<?php echo $imagePath;?>
<div id="video_thumbnail">
<a href="#" class="thumbnail">
<?php echo '<img src="' . $imagePath . '">'; ?>
<img src="<?php echo file_dir . '/' . $imagePath; ?>" height="100" width="100"/>
</a>
</div>
</div>
<?php } ?>
</div>
unless file_dir is a constant using DEFINE, I suspect it's because you didn't put a $ in front of it $file_dir
You are also displaying two files. One with the file path and one without.
Chances are, the mysql query is returning a path which is not linked ....
ie <image src="myImage.jpg" /> is not the same as <image src="images/myImage.jpg" />
As #pmahomme said, right click the element and check the pat and if need be add the additional requirements
I´m trying to style the following php echo
<a href="" title="<?php
echo"
<div class='test'>".$name."</div>'/n'
<div class='test2'>".$itemLevel."</div>'/n'
";
?>">Test Link</a>
But i think i don´t insert the div class and the '/n' at the right place. Could anyone help me?
You don't echo the HTML content inside the a href's title.
This will work:
<a href=""><?php echo"
<div class='test'>".$name."</div>'/n'
<div class='test2'>".$itemLevel."</div>'/n'
";
?>Test Link</a>
Optimizing your code:
<?php echo '
<a href="">
<div class="test">'.$name.'</div>
<div class="test2">'.$itemLevel.'</div>
Test Link</a>';
You must encode your html in order to put it into the title property
<?php
$title = '<div class="test">'.$name.'</div>' . PHP_EOL .
'<div class="test2">'.$itemLevel.'</div>' . PHP_EOL;
?>
Test Link
I'm working on a new WordPress theme (haven't touched WP themes since like 2.8...) and I'm attempting to make an if/else statement that changes the behavior of my top navigation bar based on whether the page is a front_page or not.
Essentially what I'm after is if the page is a front_page, then display the logo image. If the page is any other kind of page, then display a simple H1 element with the company name:
<li class="name">
<?php
if (is_front_page()) {
echo '<a href="<?php bloginfo("url"); ?>';
echo '<img src="' .bloginfo( "template_directory" ). '/images/logo-dsi.png" alt="DSI" />';
echo '</a>';
} else {
echo '<a href="' .home_url(). '">';
echo '<h1 class="logo">DSI</h1>';
echo '</a>';
}
?>
</li>
The else statement is working fine. But my if statement is not producing the img tag correctly. It echoes the literal bloginfo('template_directory') url and not inserting that into the img src, which is what I want it to do. It's trying to find an image at this url: localhost/images/logo-dsi.png
Obviously my syntax on line 5 is wrong somewhere, but I'm also not sure if I'm going about this the right way. Is there a better solution to what I'm trying to accomplish here?
Thanks!
The later is correct however
echo '<a href="<?php bloginfo("url"); ?>';
Should be
echo '<a href="' . bloginfo("url") . '">';
I tried this out and it worked:
<li class="name">
<a href="<?php bloginfo('url'); ?>">
<?php
if (is_front_page()) { ?>
<img src="<?php bloginfo('template_directory'); ?>/images/logo-dsi.png" alt="DSI" />
<?php
} else { ?>
<h1 class="logo">DSI</h1>
<?php } ?>
</a>
</li>
Apologies, I should have hacked away at it a little longer. But maybe this will become helpful to someone else.
I knew echos in WordPress looked bad for a reason... ;-)
Also I'm sure there's a prettier way to write this out, but for now, that code does the trick.
I'm using FancyBox to contain my iframes, but it only works for the first array. Here's what the array looks like:
$gallery_items = array(
array("img_src" => "gallery/thumb_1.jpg", "link" => "gallery/profile1.txt"),
array("img_src" => "gallery/thumb_2.jpg", "link" => "gallery/profile2.txt"),
and so on, and then here is how it is produced:
echo '<li><a id="various3" href ="' . $current_gallery_item["link"] . '"><img src="' . $current_gallery_item["img_src"] . '" /></a></li>';
the id="various3" is how FancyBox tells its an iframe. But, it only works for the first array.
Revised answer:
It seems you don't want iFrames but just load the content via Ajax. Your problem is that every element has the same ID. If you attach Fancybox via
$('#various3').fancybox();
then it will only be applied to the first element, because IDs have to be unique.
Use classes instead:
<ul>
<?php foreach($gallery_items as $item): ?>
<li>
<a class="various3" href ="<?php echo $item['link']; ?>">
<img src="<?php echo $item["img_src"]; ?>" />
</a>
</li>
<?php endforeach;?>
</ul>
And jQuery:
$('a.various3').fancybox();
If you really want to have iFrames, you can just add the iframe class to the link elements:
<a class="various3 iframe" ...>
This will automatically tell Fancybox to use iFrames.
See also Fancybox - How to use.
foreach($gallery_items as $current_gallery_item){
echo '<li><a id="various3" href ="' . $current_gallery_item["link"] .
'"><img src="' . $current_gallery_item["img_src"] . '" /></a></li>';
}
Might work
You used the same id (namely, "various3") for several elements.
This will not work this way.
Every id should be unique.
assign some class to A-tags and use it:
$("#various3")
--->
$(".various3")
