$pages=mysql_query("SELECT CP.page_id, pagename FROM cluster_pagetbl as
CP,
pagetbl WHERE
CP.cluster_id = '$id' AND CP.page_id=pagetbl.page_id order by page_id");
/*
SQL Result for $id=1:
page_id pagename
1 breakingnews
3 weather
*/
if (mysql_Numrows($pages)0) {
$prows=mysql_NumRows($pages);
$i=0;
while ($i$prows){
//figure out how to get page ids into array
$pid= mysql_result($pages,$i, page_id);
$pagename =mysql_result($pages, $i, pagename);
$pgids= array("$pid" = "$pagename");
This is *rebuilding* the array from scratch on each "page".
foreach($pgids as $pid = $pagename){
print $pid.' = '.$pagename.'br';
}
This is *inside* the loop, so shows you the first array, with page 1, and
then the second array, with page 3.
But you never really had an array with *both* pages in it at once.
Change the $pgids = array($pid = $pagename);
line to just:
$pgids[$pid] = $pagename;
Now, since you probably want $pgids to be an array even if there are *no*
pages matching the criteria, insert a line *before* the loop:
$pgids = array();
This will guarantee that $pgids is always an array.
/* prints:
1 = breakingnews
3 = weather
At this point the correct number of values appear to be in the pgids array
*/
$i++;
}
}
$query2=mysql_query("select page_id, pagename FROM
pagetbl order by page_id");
/*
SQL Result:
page_id pagename
1 breakingnews
2 pastnews
3 weather
*/
You'll want to reset($pgids) before you use it again.
if (mysql_Numrows($query2)0) {
$numrows=mysql_NumRows($query2);
$x=0;
while ($x$numrows){
$mpid=mysql_result($query2,$x, page_id);
$mpagename=mysql_result($query2,$x, pagename);
$mpgids= array("$mpid" = "$mpagename");
foreach ($mpgids as $mpid = $mpagename){
print 'input type=checkbox name=page_ids[] value="'.$mpid.'"';
if ($pgids == $mpgids){ print " checked"; }
You need to keep track of which $pgid[] you are on -- Keep a running counter
or something so that after you have $pgids[1] and $mpgids[1], you'll know
that you are on $pgids[3] and $mpgids[2], and then $pgids[3] (still) and
$mpgids[3].
In other words, you need two distinct iterators going in parallel.
print ''.$mpagename;
}
// prints out three checkboxes, since that's the total number of pages
present
//but only the third checkbox (weather) gets checked, the first one should
be checked also
$x++;
}
}
file://I used the array intersect function to doublecheck what is going on
and it
finds only weather also
file://What is happening to the first value?
$diff = array_intersect($mpgids,$pgids);
foreach ($diff as $element){
print 'p'.$element.'br';}
file://prints: weather
