now, you can type in any url in http://www.uspie.net/getimgs.php to get images. I have set my script to filter out smaller images from webpage design such as corners, spacers, etc. Currently, images smaller than 150px width and 40px height are filtered out. Large images are also scaled proportionally.
I wonder how to make the images out as radio buttons for users to choose from, anyone can give me a hint on this??
thanks!
Edit on July 17, 2008:
Here's the mod:
1. In your submit.php file, find the function do_submit1, around line 211 (or somewhere after the code: $linkres->status='discard';
$linkres->author=$current_user->user_id;
$linkres->store()
, add
PHP Code:
//catch images on destination url
$pageString = @file_get_contents($url);
preg_match_all('|<img .*?>|s', $pageString, $matches);
//the array $matches[0] now contains the img tags, let's echo 'em:
$fulldomain = 'http://www.'. $domain;
$newimages = array(); //initialize an array as image container
foreach ($matches[0] as $path){
preg_match('/src="([^"]+)"/',$path, $b); //get the image path by $b[1], however, will need to detect relative paths and convert to absolute paths
$location = $linkres->relative2absolute($fulldomain, $b[1]);//this is to convert relative image paths to absolute image paths
$filteredimg = $linkres->filterimage($location, 120, 120);
if ($filteredimg) {
$image = $linkres->scaleimage($filteredimg, 100, 100); //scale bigger images and filter out images smaller than 100x100. You can modify the picture dimensions limit based on your needs.
$newimages[] = array(
'url' => $location,
'img_tag' => $image,
);
}
}
$main_smarty->assign('newimages', $newimages);
//end of get images
PHP Code:
//reset link_field1 as $product_image
if(!empty($product_image_manual)){ //entered manually by user
$linkres->link_field1 = $product_image_manual;
}
else {
if(!empty($linkres->product_image)){
$linkres->link_field1 = $linkres->product_image; //use link_field1 to store the image path
}
}
PHP Code:
//Tony, get images 20080226
function relative2absolute($absolute, $relative) {
$p = @parse_url($relative);
if(!$p) {
//$relative is a seriously malformed URL
return false;
}
if(isset($p["scheme"])) return $relative;
$parts=(parse_url($absolute));
if(substr($relative,0,1)=='/') {
$cparts = (explode("/", $relative));
array_shift($cparts);
} else {
if(isset($parts['path'])){
$aparts=explode('/',$parts['path']);
array_pop($aparts);
$aparts=array_filter($aparts);
} else {
$aparts=array();
}
$rparts = (explode("/", $relative));
$cparts = array_merge($aparts, $rparts);
foreach($cparts as $i => $part) {
if($part == '.') {
unset($cparts[$i]);
} else if($part == '..') {
unset($cparts[$i]);
unset($cparts[$i-1]);
}
}
}
$path = implode("/", $cparts);
$url = '';
if($parts['scheme']) {
$url = "$parts[scheme]://";
}
if(isset($parts['user'])) {
$url .= $parts['user'];

$url .= ":".$parts['pass'];
}
$url .= "@";
}
if(isset($parts['host'])) {
$url .= $parts['host']."/";
}
$url .= $path;
return $url;
}
function filterimage($location, $minW=NULL, $minH=NULL){
$img = @getimagesize($location);
if ($img){ //if image exists
$w = $img[0];
$h = $img[1];
if ($w >= $minW && $h >= $minH){ //only if images greater than the minimums are they returned, otherwise, no
return $location;
}
else {
return false; //return no images
}
}
}
function scaleimage($location, $maxw=NULL, $maxh=NULL, $alt=NULL, $title=NULL){
$img = @getimagesize($location);
if($img){
$w = $img[0];
$h = $img[1];
$dim = array('w','h');
foreach($dim AS $val){
$max = "max{$val}";
if(${$val} > ${$max} && ${$max}){
$alt = ($val == 'w') ? 'h' : 'w';
$ratio = ${$alt} / ${$val};
${$val} = ${$max};
${$alt} = ${$val} * $ratio;
}
}
return("<img src='{$location}' alt='{$alt}' width='{$w}' height='{$h}' title='{$title}'/>");
}
}
//enf of get images

For you to see the mod in action, you can take a look at my website DealsPiggy / Hot Deals or see this script stand-alone here: http://www.dealspiggy.com/getimgs.php
Good luck!
