I have a URL string as follows:
compare.php?use_url=on&zipcode=London&categories%5B%5D=2&categories%5B%5D=4&categories%5B%5D=5&radius=0&checkboxnational=1&lat=50.8104415&lng=-2.99781710000002&outcode=EX13
What I am doing is converting this to hidden form elements via the following code, which I modified for arrays:
foreach($_GET as $key => $value) {
// Handle cases where QS argument is an array - for instance, "?cat[]=1&cat[]=2"
if (is_array($value)) {
foreach ($value as $k => $v) {
echo "<input type='hidden' name='$key' value='$v' />";
}
} else {
echo "<input type='hidden' name='$key' value='$value' />";
}
}
The page breaks. The strange thing is that ALL the hidden fields are being injected into the page:
and when I look in the log I find the error:
Object of class stdClass could not be converted to string
which is refering to the else part of the code. I have been reading about this error, it's the first time I've encountered it as a hobby developer. I have tried wrapping the input field in parentheses as follows:
echo("<input type='hidden' name='$key' value='$value'/>");
but no luck. I got this function via the SO page submitting a GET form with query string params and hidden params disappear and no-one mentioned this isssue. Can anyone help me out here? Thanks.
EDIT1: some of the comments have asked for the line 295 on storelocator.php. It is the line :
echo "<input type='hidden' name='$key' value='$value' />";
on the above foreach statement. Thanks.
EDIT2 ok so thanks to @Alexander in the comments I did an echo var_dump($_GET) and got the following:
array(15) { ["use_url"]=> string(2) "on" ["zipcode"]=> string(26) "Smallridge Road, Axminster" ["categories"]=> array(3) { [0]=> string(1) "2" 1=> string(1) "4" [2]=> string(1) "5" } ["radius"]=> string(1) "0" ["checkboxnational"]=> string(1) "1" ["lat"]=> string(10) "50.8104415" ["lng"]=> string(17) "-2.99781710000002" ["swlat"]=> string(9) "50.800220" ["swlng"]=> string(9) "-3.013988" ["nelat"]=> string(9) "50.820661" ["nelng"]=> string(9) "-2.981639" ["outcode"]=> string(4) "EX13" ["lat_lon"]=> object(stdClass)#4 (4) { ["lat"]=> string(10) "50.8104415" ["lon"]=> string(17) "-2.99781710000002" ["citybounds"]=> object(stdClass)#5 (2) { ["northeast"]=> object(stdClass)#6 (2) { ["lat"]=> float(50.820661) ["lon"]=> float(-2.981639) } ["southwest"]=> object(stdClass)#7 (2) { ["lat"]=> float(50.80022) ["lon"]=> float(-3.013988) } } ["outcode"]=> string(4) "EX13" } ["allproduct"]=> int(16) ["allnational"]=> int(16) }
I never realised that $_GET contained so much more than what was shown in the URL string. Can anyone advise me on how I can input only those parameters that are in the URL into hidden form elements? Thanks
EDIT3 ok so after realising that my $_GET contains so much more than the URL string, I went down the route of grabbing the URL, passing the parameters into an array, and then running the foreach statement, as follows:
$myurl = $_SERVER["REQUEST_URI"];
$separator = parse_url($myurl);
// $queryb gives the url from url=on and onwards
$parameters = $separator['query'];
parse_str($parameters, $parameter);
// $arrb is the array of the URL
$array = $parameter;
//echo var_dump($arrb);
foreach($array as $key => $value) {
if (($key != "sortbar") && ($key != "checkboxdc")) {
// Handle cases where QS argument is an array - for instance, "?cat[]=1&cat[]=2"
if (is_array($value)) {
foreach ($value as $k => $v) {
echo('<input type="hidden" name="' . $key . '[]" value="' . $v . '" />');
}
} else {
echo('<input type="hidden" name="' . $key . '" value="' . $value . '" />');
}
}
}
