list images from directory by function
- by osc2nuke
i'm using this function:
function getmyimages($qid){
$imgdir = 'modules/Projects/uploaded_project_images/'. $qid .''; // the directory, where your images are stored
$allowed_types = array('png','jpg','jpeg','gif'); // list of filetypes you want to show
$dimg = opendir($imgdir);
while($imgfile = readdir($dimg))
{
if(in_array(strtolower(substr($imgfile,-3)),$allowed_types))
{
$a_img[] = $imgfile;
sort($a_img);
reset ($a_img);
}
}
$totimg = count($a_img); // total image number
for($x=0; $x < $totimg; $x++)
{
$size = getimagesize($imgdir.'/'.$a_img[$x]);
// do whatever
$halfwidth = ceil($size[0]/2);
$halfheight = ceil($size[1]/2);
$mytest = 'name: '.$a_img[$x].' width: '.$size[0].' height: '.$size[1].'<br /><a href="'. $imgdir .'/'.$a_img[$x].'">'. $a_img[$x]. '</a>';
}
return $mytest;
}
And i call this function between a while row as:
$sql_select = $db->sql_query('SELECT * from '.$prefix.'_projects WHERE topic=\''.$cid.'\'');
OpenTable();
while ($row2 = $db->sql_fetchrow($sql_select)){
$qid = $row2['qid'];
$project_query = $db->sql_query('SELECT p.uid, p.uname, p.subject, p.story, p.storyext, p.date, p.topic, p.pdate, p.materials, p.bidoptions, p.projectduration, pd.id_duration, pm.material_id, pbo.bidid, pc.cid FROM ' . $prefix . '_projects p, ' . $prefix . '_projects_duration pd, ' . $prefix . '_project_materials pm, ' . $prefix . '_project_bid_options pbo, ' . $prefix . '_project_categories pc WHERE p.topic=\''.$cid.'\' and p.qid=\''.$qid.'\' and p.bidoptions=pbo.bidid and p.materials=pm.material_id and p.projectduration=pd.id_duration');
while ($project_row = $db->sql_fetchrow($project_query)) {
//$qid = $project_row['qid'];
$uid = $project_row['uid'];
$uname = $project_row['uname'];
$subject = $project_row['subject'];
$story = $project_row['story'];
$storyext = $project_row['storyext'];
$date = $project_row['date'];
$topic = $project_row['topic'];
$pdate = $project_row['pdate'];
$materials = $project_row['materials'];
$bidoptions = $project_row['bidoptions'];
$projectduration = $project_row['projectduration'];
//Get the topic name
$topic_query = $db->sql_query('SELECT cid,title from '.$prefix.'_project_categories WHERE cid =\''.$cid.'\'');
while ($topic_row = $db->sql_fetchrow($topic_query)) {
$topic_id = $topic_row['cid'];
$topic_title = $topic_row['title'];
}
//Get the material text
$material_query = $db->sql_query('SELECT material_id,material_name from '.$prefix.'_project_materials WHERE material_id =\''.$materials.'\'');
while ($material_row = $db->sql_fetchrow($material_query)) {
$material_id = $material_row['material_id'];
$material_name = $material_row['material_name'];
}
//Get the bid methode
$bid_query = $db->sql_query('SELECT bidid,bidname from '.$prefix.'_project_bid_options WHERE bidid =\''.$bidoptions.'\'');
while ($bid_row = $db->sql_fetchrow($bid_query)) {
$bidid = $bid_row['bidid'];
$bidname = $bid_row['bidname'];
}
//Get the project duration
$duration_query = $db->sql_query('SELECT id_duration,duration_value,duration_alias from '.$prefix.'_projects_duration WHERE id_duration =\''.$projectduration.'\'');
while ($duration_row = $db->sql_fetchrow($duration_query)) {
$id_duration = $duration_row['id_duration'];
$duration_value = $duration_row['duration_value'];
$duration_alias = $duration_row['duration_alias'];
}
}
echo '<br/><b>id</b>--->' .$qid. '<br/><b>uid</b>--->' .$uid. '<br/><b>username</b>--->' .$uname. '<br/><b>subject</b>--->'.$subject. '<br/><b>story1</b>--->'.$story. '<br/><b>story2</b>--->'.$storyext. '<br/><b>postdate</b>--->'.$date. '<br/><b>categorie</b>--->'.$topic_title . '<br/><b>project start</b>--->'.$pdate. '<br/><b>materials</b>--->'.$material_name. '<br/><b>bid methode</b>--->'.$bidname. '<br/><b>project duration</b>--->'.$duration_alias.'<br /><br /><br/><b>image url</b>--->'.getmyimages($qid).'<br /><br />';
}
CloseTable();
the result outputs only the "last" file from the directories.
if i do a echo instead of a return $mytest; it read the whole directory but ruïns the output.
