Lūdzu palīdzību php kļūdu novēršanā

Recommended Posts

Labdien,

Izmantoju šādu skriptu, kas no saišu saraksta ģenerē dažas, kuras attēlot.

<?php
function dodosrandgen() {
// set number of links you want to show at once
$show_link = 2;
// separate the links by, i.e. comma would be ",";
$separator = " ";

define('link', 'link');  
define('priority', 'priority');  

	

	$links[0]['link'] = "<li><a href=\"http://www.delfi.lv/\">Delfi</a></li>";
	$links[0]['priority'] = 5;
	$links[1]['link'] = "<li><a href=\"http://tvnet.lv/\">Tvnet</a></li>";
	$links[1]['priority'] = 1;
	$links[2]['link'] = "<li><a href=\"http://php.lv\">Php</a></li>";
	$links[2]['priority'] = 2;
	$links[3]['link'] = "<li><a href=\"http://apollo.lv/\">Apollo</a></li>";
	$links[3]['priority'] = 3;
	$links[4]['link'] = "<li><a href=\"google.com/\">Google</a></li>";
	$links[4]['priority'] = 4;



// HERE COMES THE BODY 
if($links) {
	for($i = -1; $i < count($links); $i++) {
		for($j = 0; $j < $links[$i]['priority']; $j++) {
			$newlinksindex = count($newlinks) + 1;
			$newlinks[$newlinksindex] = $links[$i]['link'];
		}
	}
} // end of if link exist

// debug
	if($show_link >= count($newlinks))
		$show_link = count($newlinks);

$showarray[0] = "";
$showindex = 0;
// Select a random element from the new array
	do {
		$randindex = rand(0, count($newlinks));
		if(!in_array($newlinks[$randindex], $showarray) && $newlinks[$randindex] != "") {
			$showarray[$showindex] = $newlinks[$randindex];
			//print_r($showarray);
			$showindex++;
		}
	}while(count($showarray) <= $show_link);

// finally print out
	for($i = 0; $i < $show_link; $i++ ) {
		if($show_link == 1 || (($i + 1) == $show_link))
			print $showarray[$i];
		else
			print $showarray[$i].$separator;
	}
//print_r($ranarray);
//print_r($links);
//print_r($newlinks);
	
} // end of the dodosrandgen function
?>

<?php dodosrandgen();?>

Skriptam ir šādas problēmas:

Quote

Notice: Undefined offset: -1 in /home2/domain/public_html/a.php on line 28

Notice: Undefined variable: newlinks in /home2/domain/public_html/a.php.php on line 29

Paša mēģinājumi tās novērst noved pie vēl sliktāka iznākuma. Priecāšos par palīdzību. Paldies.

Kāpēc tev 27. rindā $i sāk skaitīt ar -1? Tak noticē teikts, ka 28. rindā mēģini masīvam dabūt elementu ar indeksu -1.

Un otrajā noticē teikts, ka mēģini izmantot mainīgo, kurš nekur iepriekš nav definēts.

Iesaku palasīt PHP manuāli par masīviem! Uzzināsi daudz jauna!
