Help with conditional array

[htcilt]

Hi all,

I'm new to PHP and a bit stuck with a multidimensional array.
I have an array as follows (made up data just to get my problem across):

PHP Code:

$checkboxes = array(
   array(0,"box1","Select All"),
   array(1,"box2","Monday"),
   array(2,"box3","Tuesday"),
   array(3,"box4","Wednesday"),
   array(4,"box5","Thursday")
); 


I need to echo the following and in this order:

1) Checkbox1 with added Javascript function
2) Checkbox 2
3) Checkbox 3 with opening DIV
4) The remaining x number of boxes.

So in HTML looks something like this:

<label><input type='checkbox' name='days[]' value='box1' onClick='checkUncheckAll(this);' />[0]Select All Days</label><br />
<label><input type='checkbox' name='days[]' value='box2' />[1]Monday</label><br />
<label><input type='checkbox' name='days[]' value='box3' />[2]Tuesday</label><br /><div id='mydiv'>"
<label><input type='checkbox' name='days[]' value='box4'' />[3]Wednesday</label><br />"
<label><input type='checkbox' name='days[]' value='box5'' />[4]Thursday</label><br />"

The box names may change so I need to try and use keys where possible.

Is anyone able to help?
Thanks in advance

Could you show an example of the output you want?
you could use something like the following format

PHP Code:

foreach($checkboxes as $val) {
    switch($val[0]) {
        case 0:
            echo 'checkbox 0 code here<br />';
            break;
        case 1:
            echo '<strong>checkbox 1 code here</strong><br />';
            break;
        case 2:
            echo '<div>checkbox 2 code here</div><br />';
            break;
    }
}

try this;

PHP Code:

$checkboxes = array( 
   array(0,"box1","Select All"), 
   array(1,"box2","Monday"), 
   array(2,"box3","Tuesday"), 
   array(3,"box4","Wednesday"), 
   array(4,"box5","Thursday") 
);

foreach($checkboxes As $Array){
    if($Array[0] == 0){
        echo "<input type='checkbox' name='days[]' value='" . $Array[1] . "' onClick='checkUncheckAll(this);' />" . $Array[2] . "<br />\n";
    } elseif($Array[0] == 2){
        echo "<input type='checkbox' name='days[]' value='" . $Array[1] . "' " . $Extra . " />" . $Array[2] . "<br /><div id='mydiv'></div>\n";
    } else {
        echo "<input type='checkbox' name='days[]' value='" . $Array[1] . "' />" . $Array[2] . "<br />\n";
    }
}

Wouldn't a foreach work?

PHP Code:

$js = ' onClick="blah();"';
$output = '';
foreach ($checkboxes as $checkbox)
{
  $output .= '<label><input type="checkbox" name="days[]" value="'.$checkbox[1].'"'.($checkbox[0] == 0 ? $js : '').'/>['.$checkbox[0].']'.$checkbox[2].'</label><br />';
} 


Something like that, anyway.

Ha! 3 answers at once. Take your pick!

I'd say that foreach is the one thing we could all agree on

[JAY6390]

Indeed it is
I would recommend restructuring the array though tbh

[htcilt]

all give foreach a go and get back to you.
Thanks everyone with your suggestions so far.

JAY6390, I'm all ears if you have a better structure

[angst]

I don't really see any issues with the array, though you don't really need to number them, php does that for you.

[JAY6390]

I like it when checkboxes are more ordered and have useful keys

PHP Code:

$checkboxes = array(
    0 => array(
        'name' => 'box1',
        'text' => 'Select All',
        'tags' => "onClick='checkUncheckAll(this);'"
    ),
    1 => array(
        'name' => 'box2',
        'text' => 'Monday',
    ),
    2 => array(
        'name' => 'box3',
        'text' => 'Tuesday',
    ),
    3 => array(
        'name' => 'box4',
        'text' => 'Wednesday',
    ),
    4 => array(
        'name' => 'box5',
        'text' => 'Thursday',
    )
);

foreach($checkboxes as $id => $data) {
    echo '
<label><input type="checkbox" name="days[]" value="'.$data['name'].'"'.(isset($data['tags']) ? ' '.$data['tags'] : '').'/>['.$id.']'.$data['text'].'</label>';
    if($id == 2)
        echo '<div id="myDiv">';
} 


This outputs

<label><input type="checkbox" name="days[]" value="box1" onClick='checkUncheckAll(this);'/>[0]Select All</label>
<label><input type="checkbox" name="days[]" value="box2"/>[1]Monday</label>
<label><input type="checkbox" name="days[]" value="box3"/>[2]Tuesday</label><div id="myDiv">
<label><input type="checkbox" name="days[]" value="box4"/>[3]Wednesday</label>
<label><input type="checkbox" name="days[]" value="box5"/>[4]Thursday</label>

Oops, a couple of things. Change

PHP Code:

'tags' => "onClick='checkUncheckAll(this);'"
// to
'tags' => 'onClick="checkUncheckAll(this);"' 


and also add <br /> to the end of the echo statement after </label>

Thanks everyone for your posts. Its been a huge help

[htcilt]

I've run into a slight problem. When the "Select All" option is selected, all checkboxes get selected using the checkUncheckAll function. The problem with this is the value of each checkbox is posted, whereas I just need the value "all" from the 1st checkbox.

A way around this would be to disable all other checkboxes on the 1st checkbox is ticked.

Is it possible to integrate this in the code we already have?

[JAY6390]

You could just check that the first checkbox is set, or alternatively give that checkbox a new value such as
name="checkALL"
Then in your php check to see if that value is set before checking the other values

PHP Code:

if(isset($_POST['checkALL'])) {
    // code for all checked here
}else{
    // code for individual checkboxes here
}

Good idea JAY6390. Never thought of doing it that way
