Invoking Taxonomy Image

To display a taxonomy image from your themeFor web sites, this refers to the "look and feel" of the site. It is also used to describe the code to produce that look. or other phpRecursive acronym for "PHP: Hypertext Preprocessor" - is a widely-used Open Source general-purpose scripting language that is especially suited for Web development and can be embedded into HTML. code, add a call to the taxonomy_image_display function. This function requires that you pass the term id of the term for which you wish to display the appropriate image. For example: taxonomy_image_display($term->tid).
This will return an <img> tag with the appropriate values for "src=," "height=," "width=," and "alt=." For example, it may return something like: <img src="files/image.jpg" width="75" height="75" alt="term-name" title="term-description">. If there is no associated image, it will return NULL (unless you are using "Recursive image display" and the term's parent has an associated image).
If you wish to set other IMG attributes, Taxonomy_image_display may be called with an associative (indexed) array of attributes. If an attribute is the same as one of the computed attributes (width, height, alt, title), the supplied attribute will be used.
For example, taxonomy_image_display($term->tid, array('border' => '2', 'hspace' => '5')
This would then return the following "IMG" tag: <img src="files/image.jpg" width="75" height="75" alt="term-name" title="term-description" border="2" hspace="5" />

How Can I Use Taxonomy Image?
Modify Your ThemeFor web sites, this refers to the "look and feel" of the site. It is also used to describe the code to produce that look.
To actually display images from your themeFor web sites, this refers to the "look and feel" of the site. It is also used to describe the code to produce that look., you will have to modify the themeFor web sites, this refers to the "look and feel" of the site. It is also used to describe the code to produce that look. to make a call to taxonomy_image_display. When calling this function, you will need to pass in the taxonomy term for which an image should be displayed. For example, from your themeFor web sites, this refers to the "look and feel" of the site. It is also used to describe the code to produce that look.'s "_node" function you might do the following:
foreach (taxonomy_node_get_terms($node->nid) as $term) {
if ($image = taxonomy_image_display($term->tid)) {
$output .= "$image";
}
}Taxonomy Term Links as Pictures
If you'd like to replace the taxonomy term links that display with your content by pictures, you can use hook_link_alter to change the linkThe technique which points to another page, anywhere on the Internet, from the current page. text into IMG tags.
Note: if you want to do this, you should either scale the images down, or load small images to start with. A reasonable maximum size for images used as links is about 64 pixels on each side. If they are bigger than this, they will dominate the display.
function mymodule_link_alter(&$node, &$links) {
// this code is to eliminate TAC_Lite links in images - it really doesn't belong here
foreach ($links AS $module => $link) {
if (strstr($module, 'taxonomy_term')) {
$tid = substr($module, 14);
$term = taxonomy_get_term($tid);
$tname = $term->name;
// See if we have a taxonomy image associated with this term
$taxo_image = taxonomy_image_display($term->tid);
if ($taxo_image) {
$links[$module]['title'] = $taxo_image;
$links[$module]['html'] = TRUE;
} /* end image insertion */
} /* end if taxonomy_term */
} /* end foreach */
}Prefix a Teaser View with an Image
Another commonly sought use is to prefix a teaser view with an image. This can be done in the hook_nodeapi(op=view) function.
function mymodule_nodeapi(&$node, $op, $a3 = NULL, $a4 = NULL) {
if ($node->type != 'pinkslip') { return; } /* don't do any others */
if ($op == 'view') {
$termlist = taxonomy_node_get_terms($node->nid);
$terms = array();
foreach ($termlist as $key => $term) {
$taxo_image = taxonomy_image_display($term->tid, "border='0', hspace='5', vspace='5'")
if ($taxo_image) {
// Quit when we find the first one
break;
}
}
// Prepend the teaser with the IMG tag
$node->content['teaser']['#value'] = $taxo_image . $node->content['teaser']['#value']
}
}
