eek!not handling the array right!
so i have an associative array that i need to make into an html string.... my way of doing it before was to pop in and out of php and using a foreach to loop through... that foreach loop is in the function i'm trying to make. (there's several of them in the sign up and i need to make them into options to use in the search as well.) now my issue is that the function doesn't work right... i have a test page that's just supposed to make a string out of an array that i'm using to test it...
here's the function (carriage retun in the debug string and for the comment added to stop horizontal scroll)
<?php
function array_to_options($array, $method, $feild_name){
echo \"in ato, feild name $feild_name; method $method; array $array <br />
{$$method}[$feild_name] <br />\"; # debug
$optlist=array(); # make an empty array
foreach($array as $key=>$value){
if($method[$feild_name]==$key){
# if this is the first time it wont match, so we don't need to care if it's set
$optlist[]=\"<option value=\\"$key\\" selected>$value</option>\";
}else{
$optlist[]=\"<option value=\\"$key\\">$value</option>\";
}
}
return $optlist;
}
?>Quote: in ato, feild name month; method $_POST; array Array
$_POST[month]
Array

$optlist is an array, though, not a string variable?
If you want it to be a string variable, remove the []. ??
<?php
function array_to_options($array, $method, $feild_name){
_echo \"in ato, feild name $feild_name; method $method; array $array <br />
{$$method}[$feild_name] <br />\"; # debug
_foreach($array as $key=>$value){
____if($method[$feild_name]==$key){
# if this is the first time it wont match, so we don't need to care if it's set
______echo \"<option value=\\"$key\\" selected>$value</option>\";
____}else{
______echo \"<option value=\\"$key\\">$value</option>\";
____}
__}
}
?>
Or use =. to run them all together?

i realized that.[blush]
yes i am trying to get a string. =. doesn't seem to work. that made an error.
but $optlist=$optlist."$value";
does work.. to some extent.
the default selected thing doesn't seem to work
new code:
<?phpfunction array_to_options($array, $method, $feild_name){
echo \"in ato, feild name $feild_name; method $method; array $array
<br /> {$method}[$feild_name] <br />\"; # debug
$optlist=''; # make an empty string
foreach($array as $key=>$value){
if($method[$feild_name]==$key){
# if this is the first time it wont match, so we don't need to care if it's set
$optlist=$optlist.\"<option value=\\"$key\\" selected>$value</option>\";
}else{
$optlist=$optlist.\"<option value=\\"$key\\">$value</option>\";
}
}
return $optlist;
}
?>
<?phpinclude(\"/home/joshua/includes/fyd.incs.php\"); # includes file
$month=$_POST['month'];
if(!isset($month)){
echo <<<END
<html><head></head><body>
<form action=\"$_SERVER[PHP_SELF]\" method=\"post\">
<input type=\"text\" name=\"month\">
<input type=\"submit\" value=\"check\">
</form>
</body></html>
END;
}else{
/* array dropped from here & chopped up to stop scrolling */
$array=array('00'=>'Month', '01'=>'January', '02'=>'February', '03'=>'March',
'04'=>'April', '05'=>'May', '06'=>'June', '07'=>'July',
'08'=>'August', '09'=>'September', '10'=>'October', '11'=>'November', '12'=>'December');
$method='$_POST';
$feild_name=\"'month'\";
$list=array_to_options($array, $method, $feild_name);
echo '<select name=\"test\" size=\"1\">'.$list.'</select>';
}
?>
it should have gotten the value of 12 since that's what i typed in

I have trouble with $variable and $_POST['variable'] -- they are the same thing. Perhaps set $thismonth=$_POST['month']?

now the test file looks like
<?phpinclude(\"/home/joshua/includes/fyd.incs.php\"); # includes file
$month=$_POST['month'];
if(!isset($month)){
echo <<<END
<html><head></head><body>
<form action=\"$_SERVER[PHP_SELF]\" method=\"POST\">
<input type=\"text\" name=\"month\">
<input type=\"submit\" value=\"check\">
</form>
</body></html>
END;
}else{
$array=array('00'=>'Month', '01'=>'January', '02'=>'February', '03'=>'March',
'04'=>'April', '05'=>'May', '06'=>'June', '07'=>'July',
'08'=>'August', '09'=>'September', '10'=>'October', '11'=>'November', '12'=>'December');
$method='$_POST';
$feild_name=\"'month'\";
$list=array_to_options($array, $method, $feild_name);
echo '<select name=\"test\" size=\"1\">'.$list.'</select>';
}
?>
<?phpfunction array_to_options($array, $selected){
echo \"in ato, selected: $selected; array: $array <br />\"; # debug
$optlist=''; # make an empty string
foreach($array as $key=>$value){
if($selected===$key){
# if this is the first time it wont match, so we don't need to care if it's set
$optlist=$optlist.\"<option value=\\"$key\\" selected>$value</option>\";
}else{
$optlist=$optlist.\"<option value=\\"$key\\">$value</option>\";
}
}
return $optlist;
}
?>
in ato, selected: 12; array: Array <br /><select name="test" size="1"><option value="00">Month</option><option value="01">January</option>
<option value="02">February</option><option value="03">March</option>
<option value="04">April</option><option value="05">May</option>
<option value="06">June</option><option value="07">July</option>
<option value="08">August</option><option value="09">September</option>
<option value="10">October</option><option value="11">November</option>

figured it out.. the selected value is treated as a string, so i needed == instead of ===
since i know this is useful to turn associative arrays into option code, i think i'll send it to php.net and see if they wanna add it. i'm sure those doing forms with associative arrays that want memory have already written functions, but hey, who knows...one second thought i don't see how and most problaby already have that. so... unless you people want to encourage me i'm going ot give up on that
