Check All function and Checkbox array conflict

[dasein]

I have a function in the header which simply allows for all the checkboxes of the same name to be selected:

 

function checkAll(field)

{

for (i = 0; i < field.length; i++)

field.checked = true ;

}

 

function uncheckAll(field)

{

for (i = 0; i < field.length; i++)

field.checked = false ;

}

 

But I can't use the [] brackets like this with that function.

 

<form name="test" action="testform.php" method="post">

<input type='checkbox' name='member_type[]' value='FM'>Full Member<br>

<input type='checkbox' name='member_type[]' value='JM'>Junior Member<br>

<input type='checkbox' name='member_type[]' value='LM'>Lady Member<br>

<input type='checkbox' name='member_type[]' value='MM'>Make Member<br>

<input type='checkbox' name='member_type[]' value='OM'>Outside Member<br>

<input type="submit" value="SUBMIT">

 

To run a php script to read the checkboxes as an array (there are actually about 50 with the same name), I have to have the [] brackets.

 

$types = $_POST['member_type']; // array of values selected by the user

 

foreach($types as $key=>$val){

    $types_search.=$val.", ";

}

 

I want to have both, but they seem to not work together. Is there a minor workaround to this? I hope I explained this okay. Thank you.

you can get javascript functions that check boxes based on class rather than name so that would be the way to go, then you wont mess up the PHP

Thank you, dt192. I'm not quite sure I follow you though. You're saying I should place the checkboxes in a class in a CSS file for the HTML page?

you can utilize javascript's "node" functions

 

for example

 

if you added in an id for those forms

 

lets say you id'd one 'test'

 

you could do

function checkAll(eid) {
  var children = document.getElementById(eid).childNodes;
  for (i = 0; i < children.length; i++) {
    children[i].checked = true;
  }
}

Thanks, RusselReal. It still won't work both ways.
