Get Image and text from Content was created by jianhui0215

I Like Hot News flash very much ,but it only supports static image from module setting page,so I do some work to let that get images and text from content items .

all is bellow:
first : modify mod xml file
I add some param, special is the category ID.
mod_hot_newsflash.xml

Code:

<param name="secid" type="text" default="" label="Section ID" description="PARAMSECTIONID" />
<param name="catid" type="text" default="" label="Category ID" description="PARAMCATEGORYID" />
<param name="count" type="text" default="5" label="Count" description="The number of items to display (default 5)" />
<param name="ordering" type="list" default="c_dsc" label="Ordering" description="Ordering options">
	<option value="c_dsc">Recently Added First</option>
	<option value="m_dsc">Recently Modified First</option>
</param>
<param name="limittitle" type="text" default="" label="Title Chars Limit" description="Article's Title Characters Limit" />
<param name="contentLength" type="text" default="150" label="Content Lenght" description="DESC CONTENT LENGTH" />

second ,change the default image folder to ""

Code:

<param name="imageFolder" type="text" default="" label="LABEL FOLDER" description="DESC FOLDER" />

third, modify the php code, add some functions ,let it get image,title,text from content items
mod_hot_newsflash.php
1.change the default image folder

Code:

line 35:   $imageFolder = $params->get('imageFolder','');

2.the php code

Code:

/* cancel the original method
for ($loop = 1; $loop <= 5; $loop += 1) {
$heading[$loop] = $params->get('heading'.$loop,'Lorem Ipsum');
}

for ($loop = 1; $loop <= 5; $loop += 1) {
$link[$loop] = $params->get('link'.$loop,'#');
}

for ($loop = 1; $loop <= 5; $loop += 1) {
$info[$loop] = $params->get('info'.$loop,'Lorem ipsum dolor sit amet, consectetur adipiscing elit. Nulla tincidunt condimentum lacus. Pellentesque ut diam.');
}

for ($loop = 1; $loop <= 5; $loop += 1) {
$image[$loop] = $params->get('image'.$loop,'image'.$loop.'.jpg');
}
*/
$cs=get_ArticalList($params);
//print_r($cs);
$loop=1;
foreach ( $cs as $row ) {
  ///if you title is long, you may using $heading[$loop]=JString::substr($row->title,0,$params->get(limittitle));
  $heading[$loop]=$row->title;
  $link[$loop] = $row->link;
  $text=$row->introtext .$row->fulltext;
  $c=JString::substr(html2txt($text) ,0,$params->get(contentLength));
  $info[$loop]=$c.' ...';
  
  ///grep images
  $regex   = "/<img[^>]+src\s*=\s*[\"']\/?([^\"']+)[\"'][^>]*\>/";
	$search  = $row->introtext . $row->fulltext;
	preg_match ($regex, $search, $matches);

Great, but before we test it please tell us is it for Joomla 1.5 or Joomla 1.6 version of the Hot Newsflash module?

Version 2:
now ,you can switch images from content items or from you typed as before .

Under joomla 1.5

Firest : change the xml file
1:change imageFolder the default to ""

Code:

<param name="imageFolder" type="text" default="" label="LABEL FOLDER" description="DESC FOLDER" />

2: add some params

Code:

<param type="spacer" default="Images and Contents Source Properties" />
<param name="sourceFrom" type="list" default="sql" label="LABEL Images and Contents Source From" description="DESC Images and Contents Source From">
	<option value="db">Content Item in the DB</option>
	<option value="typed">bellow typed</option>
</param>
<param name="imageSource" type="list" default="all" label="LABEL IMAGE Source" description="DESC IMAGE Source">
	<option value="all">Intro Text + Full Text</option>
	<option value="intro">Intro Text</option>
	<option value="full">Full Text</option>
</param>
<param name="contentSource" type="list" default="all" label="LABEL Content Source" description="DESC Content Source">
	<option value="all">Intro Text + Full Text</option>
	<option value="intro">Intro Text</option>
	<option value="full">Full Text</option>
</param>
 <param name="secid" type="text" default="" label="Section ID" description="PARAMSECTIONID" />
<param name="catid" type="text" default="" label="Category ID" description="PARAMCATEGORYID" />
<param name="count" type="text" default="5" label="Count" description="The number of items to display (default 5)" />
<param name="ordering" type="list" default="c_dsc" label="Ordering" description="Ordering options">
		<option value="c_dsc">Recently Added First</option>
		<option value="m_dsc">Recently Modified First</option>
</param>
<param name="contentLength" type="text" default="150" label="Content Lenght" description="DESC CONTENT LENGTH" />

2nd, modify mod_hot_newsflash.php file
1:Change the $imageFolder 's default value

Code:

$imageFolder = $params->get('imageFolder','');

2:add the code, the file is long ,so I give all the php code of the file

Code:

<?php
//no direct access
defined('_JEXEC') or die('Direct Access to this location is not allowed.');

// Path assignments
$mosConfig_absolute_path = JPATH_SITE;
$mosConfig_live_site = JURI :: base();

Any way you could help out and move the tab-links to the left instead of the right? I am loving your version of hot newsflash, perfect for what I want except for the tab-positions

Thanks in advance

Hiya all!

Do you think it's worth trying the code out on the Joomla 1.6 version of the Hot Newsflash module?
