problem with string in a function acting as array??

[ethought]

Hi All -

 

Got a problem that I cannot seem to find a fix for.

 

function list_edit($dbname,$dbfield,$submitbutton,$newvalue,$deletebutton,$deletevalues) {
include("db.php");
if(isset($submitbutton)){
	$newtype = $newvalue;
	if($newtype == ""){
		echo "You did not enter anything...? Please go back and try again.<br>";
	} else {
		$updatedb = mysql_query("INSERT INTO $dbname ( `id` , $dbfield ) VALUES ('','$newtype')", $db);
		if($updatedb){
			echo "PLant class Added Successfully. <br>";
		} else {
			echo "There was an error adding the plant class please contact admin to report error";
		}
	}
}	

if(isset($deletebutton)){
	foreach($deletevalues as $id){
		$dbname = mysql_query("DELETE FROM $dbname WHERE id='$id'", $db);
		if($deletetype){
			echo "Plant db name with id of $id has been deleted... <br>";
		} else {
			echo "There was a problem deleting plant $dbname id $id <br>";
		}
	}

}
}


### function for output of all known list vars and delete and add parts

function list_display($title,$dbname,$deletevar,$dbfield,$deletebutton,$newvalue,$addbutton){
include("db.php");
?>
<h3><? echo $title ?></h3>
<form action="<?php echo $PHP_SELF?>" method="post" enctype="multipart/form-data">
<table class=neat>
<?

$i = 0;
$gettypes = mysql_query("SELECT * FROM $dbname", $db);
while($types = mysql_fetch_array($gettypes)){
	$id = $types[id];

	echo "<tr><td><input type='checkbox' name=$deletevar[$i] value='$id'></td><td>$types[$dbfield] - Delete Var is $deletevar[$i]</td></tr>";
	$i++;
}
echo "</table>";
echo "<input type=submit name='$deletebutton' value='Delete'>";

##  ADD  FORM

echo "<table class=neat>";
echo "<tr><td>Add $title</td><td><input type=text name='$newvalue' size='40'>  <input type=submit name='$addbutton' value='Add'></td></tr>";
echo "</table>";
echo "</form>";
}

 

The thing is in the list_display function when the function names the $deletevar[$i] variables which assign a delete id to each selected plant in the form, instead of acting like normal so that

$deletevar = "deleteid";

$i = 0;

while(.......){

echo "<tr><td><input type='checkbox' name=$deletevar[$i] value='$id'></td><td>$types[$dbfield] - Delete Var is $deletevar[$i]</td></tr>";

}

 

would give me:

 

deleteid[0];

deleteid[1];

deleteid[2];

 

I am getting

 

d

e

l

e

t

e

 

as my posted delete id names....

 

I hope someone can understand what I mean and point out where I am going wrong.

 

Basically I just want to assign the value to the form of:

 

deleteid[1]

deleteid[2] etc...

 

at the moment it seems to be pulling character x from deleteid[x]

 

so my posted variables are like

 

$e = 2

$l = 3

 

???

why don't you just name like this

 

<input type='checkbox' name='delete[]' value='$id'>

[ethought]

The name of the checkbox needs to be dynamic, otherwise all my checkboxes for all 20 or so sections will have the same name, which will not work for what I am doing.

 

I want to run through and basically use:

 

foreach($_POST[deleteids] as $did){

          Do STUFF;

}

 

foreach($_POST[deletetypeids] as $dtid){

          Do STUFF;

}

 

Works perfectly when not using in a function.

 

If I just use:

 

<input type='checkbox' name='$deleteid[]' value='$id'>

 

in the function I get

 

Parse error: syntax error, unexpected ']', expecting T_STRING or T_VARIABLE or T_NUM_STRING in ...

OK figured it out -

 

Just needed to add deleteid[] to the function call NOT within the function!
