[SOLVED] PHP Array - Form Post - and Javascript

Zhadus · January 25, 2008

Ok, thank you for trying to help me in advance. First off, what I am trying to do is this. I have an autopopulated list of names with checkboxes. I also used some javascript so that I could "check all" or "uncheck all." And then I created some more javascript to output values as to whether the submit should be active or disabled. As you select names it calculates 2 person teams, and how many matches would be need for every team to play at least once. What I need is to send an array of the "checked" names to another page when I submit the form.

Here is my javascript:

function checkAll(field) {
for (i = 0; i < field.length; i++)
field[i].checked = true ;
}

function uncheckAll(field) 
{ 
for (i = 0; i < field.length; i++)
field[i].checked = false ; 
}

function tcheck(field)
{
var x=0;
for (i = 0; i < field.length; i++)
{
if (field[i].checked == true)
	x++;	
}
if (x%2==0) {
document.mainform.tdisp.value = (x/2);
if ((x/2)>1){
mcheck(x);
} else {
document.mainform.mdisp.value = "X";
document.mainform.pbutton.disabled = true;
}
} else {
document.mainform.tdisp.value = "X";
document.mainform.mdisp.value = "X";
document.mainform.pbutton.disabled = true;
}
}

function mcheck(val)
{
if ((val%2)!=0) {
val = (val+(val%2))/2;
} else {
val = val/2;
}
if ((val%2)!=0) {
val = (val+(val%2))/2;
} else {
val = val/2;
}
num = val;
document.mainform.mdisp.value = num;
document.mainform.pbutton.disabled = false;
}

and here it the page:

<html>
<head>
</head><body>
<script language=javascript src=clancomp.js>
</script>
<?php

$members = array("Name1", "Name2", "Name3", "Name4", "Name5", "Name6", "Name7", "Name8", "Name9", "Name10", "Name11", "Name12", "Name13", "Name14");
$memnum = sizeof($members);

echo "<form name=mainform action=compcalc.php method=post><table border=0 width=500><tr><td>Select Members:</td><td> </td><td><input type=button name=CheckAll value=\"Check All\" onclick=checkAll(document.mainform.memlist)></td><td><input type=button name=UnCheckAll value=\"Uncheck All\" onclick=uncheckAll(document.mainform.memlist)></td></tr>";
$count=0;
while ($count<$memnum) {
$count2=0;
echo "<tr>";
while (($count2<4) and ($members[$count+$count2]!=null)) {
	echo "<td><input type=checkbox name=memlist onclick=tcheck(document.mainform.memlist) value=" . $members[$count+$count2] . ">" . $members[$count+$count2] . "</td>";
	$count2++;
}
echo "</tr>";
$count = $count+4;
}
echo "<tr><td colspan=4> </td></tr><tr><td>Teams: <input type=text name=tdisp size=2 readonly=true></td><td>Matches: <input type=text name=mdisp size=2 readonly=true></td><td></td><td><input type=submit name=pbutton value=\"Post Teams\" disabled=true action=submit></td></tr></table></form>";
?>
</body>
</html>

Thank you guys for any help.

as you have it now. use javascript:

var boxes;

on submit, run through ALL the checkboxes.

if checked {

boxes+='+on';

else

boxes+='+off';

}

then put the boxes var in a hidden form element like

document.formname.boxesf.value=boxes;

then in php, explode the string, seperate on +
