CodeIgniter img tag

问题:

I'm using following code to display an image with CodeIgniter framework.

<?php echo img('sample/logo.png'); ?>

And this is producing following output::

<img alt="" src="http://localhost:8080/test/css/sample/logo.png">

Why it does not closes the tag with /> Also, how can i specify the alt text when i echo image? thanks

回答1:

According to user guide, it should end with />. I tried it out, and it works.

If you want a shorter tag, use this:

<?php echo img(array('src'=>'image/picture.jpg', 'alt'=> 'alt information')); ?>

Sometimes if you view source using certain browsers (firefox, chrome), it omits the /> tag. Try view source using a notepad or something, it should display proper /> tag.

$image_properties = array(
          'src' => 'sample/logo.png',
          'alt' => 'Me, demonstrating how to eat 4 slices of pizza at one time',
          'class' => 'post_images',
          'width' => '200',
          'height' => '200',
          'title' => 'That was quite a night',
          'rel' => 'lightbox',
);

img($image_properties);
// <img src="http://site.com/index.php/sample/logo.png" alt="Me, demonstrating how to eat 4 slices of pizza at one time" class="post_images" width="200" height="200" title="That was quite a night" rel="lightbox" />

Dont echo an image like that, do it like this:

echo "<img src='sample/logo.png' alt='my company name' title='my company logo' border='0' />";

Remeber the location you have there is relative, you should try to stick to absolute paths were possible eg: "/test/css/sample/logo.png" to avoid confusion.

(sorry, missed the bit where you said you were using a framework).
