JS and PHP and php arrays ...

ripman

Hello I have something like this :

<input TYPE=text name='itemid[1]' value='1' size=30 disabled>
<input TYPE=checkbox name="aktywny[]" value="1">


<input TYPE=text name='itemid[2]' value='2' size=30 disabled>
<input TYPE=checkbox name="aktywny[]" value="2">


<input TYPE=text name='itemid[3]' value='3' size=30 disabled>
<input TYPE=checkbox name="aktywny[]" value="3">

etc ...

Now I need to add onclick method to the checkbox that will ENABLE/distable the apropriate text field. I mean

checkbox that has value "1" enables/disables the text field which has the "1" VALUE.

Any ideas ?

...but shouldn't it just work like this:

ripman

I have tried but it doesn't work. What's wrong ?

<form ACTION="" name=test>
<input TYPE="abc[123a]" value='aaa' disabled> <input TYPE="checkbox" onclick="document.test.abc['123a'].enabled">
</FORM>

This has nothing to do with PHP. But even so, I'll try to help you out. 🙂

<script language="JavaScript">
<!--
function switch() {

if(document.formname.checkboxname.checked){
document.formname.textname.disabled=false;
}

else{
document.formname.textname.disabled=true;
}

}
//-->
</script>

<form action="" method="" name="test">

<input type="text" disabled size="10" name="textname">
<input type="checkbox" onclick="switch()" name="checkboxname">

</form>

ripman

my IE returns an error, it says :

document.formname.checkboxname is empty or is not an object ...

heres some piece of code that generates those fields :

while($r = mysql_fetch_object($do)){
		echo "
		<tr bgcolor=#EEEEEE>
			<td style='color:green;'><B>$r->pid</B></TD>
			<td style='color:red;'>
			<input TYPE=text name='pelnanazwa[$r->pid]' value='$r->nazwa' size=30 disabled class=formularz>
			</TD>
			<td><input TYPE=checkbox name=\"aktywny[]\" value=\"$r->pid\" class=\"womar\" onclick=\"nowe.pelnanazwa['$r->pid'].enabled\"></TD>
		</TR>";
	}

onclick=\"nowe.pelnanazwa['$r->pid'].enabled\"

Doesn't work .. 🙁

You're right, sorry. 🙂

echo <<<EOF

<script language="JavaScript">
<!--
function enable(id) {

if(document.formname.aktywny.checked){
eval("document.formname.pelnanazwa_"+id+".disabled=false");
}

else{
eval("document.formname.pelnanazwa_"+id+".disabled=true");
}
}
//-->
</script>

EOF;


while($r = mysql_fetch_object($do)){ 
        echo <<<EOF

<tr bgcolor='#EEEEEE'> 
     <td style='color:green;'><B>{$r['pid']}</B></TD> 
     <td style='color:red;'> 
      <input type='text' name='pelnanazwa_{$r['pid']}' value='{$r['nazwa']}' size='30' disabled class='formularz'> 
            </TD> 
            <td><input TYPE=checkbox name="aktywny" value="{$r['pid']}" class="womar" onclick="enable({$r['pid']});"></TD> 
        </TR>"; 

EOF;
}

I haven't really tested it, but it should work. Also, some notes: you have to get rid of the brackets in the form names (I put the id in the formname), and you can't use $r->pid because $r is not an object, it's an array (so you have to use $r['pid'] instead).

Hi,

this one works with form names that uses brackets to submit the values as array:

<html>
<head>
<script language="JavaScript">
<!--

function switchit(id) {
  chk = document.forms.test.elements["aktywny["+id+"]"];
  inp = document.forms.test.elements["itemid["+id+"]"];
  if(chk.checked){
    inp.disabled=false;
  } else{
    inp.disabled=true;
  }
}

//-->
</script>
</head>
<body>
<form action="" method="" name="test">
<input TYPE=text name='itemid[1]' value='1' size=30 disabled>
<input TYPE=checkbox name="aktywny[1]" value="1" onclick="switchit(1)">


<input TYPE=text name='itemid[2]' value='2' size=30 disabled>
<input TYPE=checkbox name="aktywny[2]" value="2" onclick="switchit(2)">


<input TYPE=text name='itemid[3]' value='3' size=30 disabled>
<input TYPE=checkbox name="aktywny[3]" value="3" onclick="switchit(3)">
</form>
</body>
</html>

At least it works with IE and Firefox.

$r is an object in this case since mysql_fetch_object is used instead of mysql_fetch_array or mysql_fetch_assoc.

Goes back to dive in the PHP manual

ripman

Thx - that works great 😃

It's high time to learn JS 😉
