So I'm trying to alphabetically order my article titles in concrete5, however, they always show the default order. I've attempted different methods of sorting before finding this documentation but it still doesn't seem to work. I'm newer to the concept of sorting something like this.
If someone could clarify how usort works --I was a bit confused by the php documentation I read. How is it making a comparison between $a and $b? I imagine this might not even be the way to go since I want its sort order to be alphabetical.
Any wisdom would be greatly appreciated.
Here is the code I'm working with:
<?php
function orderNode($a, $b) {
return strcmp($a->value, $b->value);
}
usort($artCategoryOptions, "orderNode");
?>
<?php if($urlparam == '?category=Articles' || strpos($urlparam, '?article_category') !== false) {?>
<h3>ARTICLE CATEGORIES</h3>
<ul class="nav nav-pills nav-stacked space-bottom">
<?php foreach ($artCategoryOptions as $cat) { ?>
<li class="<?php if ($artCategoriesFilter == $cat->value) echo 'active'; ?>">
<a href="/newsroom/?article_category=<?php echo $cat->value ?>">
<strong><?php echo $cat->value ?></strong>
</a>
</li>
<?php } ?>
</ul>
<?php } ?>
The vardump of $artCategoryOptions --which is what I'm trying to sort is:
object(SelectAttributeTypeOptionList)#327 (2)

I believe if you go into the Dashboard and change the "Option Order" for the attribute to "Alphabetical" it would return them in the order you want without you having to re-sort them.
I have written below lines of code
public function shiftarray($cursor, $arg)
{
$keyarguments = array("first_name","roll_no");
$arrayStudents =array();
foreach ($cursor as $k => $row)
{
foreach ($keyarguments as $key)
{
if (strcasecmp($row[$key], $arg) == 0)
{
array_unshift($arrayStudents, $row);
}
else
{
}
}
}
return $arrayStudents;
}
I have array of students in $cursor like
{ [0]=> array(50) { ["_id"]=> object(MongoId)#23 (1) { ["$id"]=> string(24) "58131c7799fbad4c1d000202" } ["student_id"]=> float(2) ["registration_temp_perm_no"]=> string(1) "1" ["roll_no"]=> float(1) ["admission_date"]=> string(10) "01/07/2016" ["first_name"]=> string(7) "Neil" ["middle_name"]=> string(4) "David" ["last_name"]=> string(6) "Stephan" ["dob"]=> string(10) "12/03/1981" ["gender"]=> string(6) "Female" ["blood_group"]=> string(2) "A+" ["birth_place"]=> string(11) "Sadar Bazar" ["nationality"]=> string(6) "Indian" ["language"]=> string(7) "English" ["religion"]=> string(8) "Agnostic" ["address_line1"]=> string(20) "4148 Hazelcrest Hill" ["address_line2"]=> string(20) "22883 Memorial Place" ["city"]=> string(11) "Sadar Bazar" ["state"]=> string(13) "Uttar Pradesh" ["pincode"]=> string(6) "190010" ["country"]=> string(5) "India" ["phone1"]=> string(10) "9039180419" ["phone2"]=> string(10) "7681559402" ["email"]=> string(24) "educianstudent#gmail.com" ["is_sms_enabled"]=> string(3) "Yes" ["is_active"]=> int(1) ["has_finished"]=> int(0) ["student_category"]=> string(1) "5" ["course"]=> string(24) "58131c7099fbad4c1d0001c2" ["Biometric_ID"]=> string(1) "1" ["siblings"]=> string(14) "Cynthia Taylor" ["guardian_name"]=> string(14) "Cynthia Taylor" ["guardian_occupation"]=> string(13) "Senior Editor" ["guardian_qualification"]=> string(20) "Research Assistant I" ["guardian_email_id"]=> string(23) "educianparent#gmail.com" ["gaurdain_contact_details"]=> string(10) "9419513603" ["guardian_relationship"]=> string(6) "Father" ["height"]=> string(3) "4.9" ["weight"]=> string(4) "34.9" ["allergies"]=> string(0) "" ["batch"]=> int(2) ["academicyear"]=> string(4) "2015" ["batchhistory"]=> array(1) { [0]=> array(5) { ["batchid"]=> float(2) ["academic_year"]=> string(4) "2015" ["course"]=> string(24) "58131c7099fbad4c1d0001c2" ["sequenceno"]=> int(1) ["courseId"]=> object(MongoId)#24 (1) { ["$id"]=> string(24) "58131c7099fbad4c1d0001c2" } } } ["uploads"]=> array(1) { ["profile_pic"]=> string(39) "58131c7799fbad4c1d000202schoolgirl2.jpg" } ["created_at"]=> NULL ["updated_at"]=> string(0) "" ["routearray"]=> array(2) { [0]=> array(5) { ["routeid"]=> int(2) ["academicyear"]=> string(4) "2016" ["current"]=> int(0) ["vehicleno"]=> string(9) "JK01S8764" ["dateofassignment"]=> string(10) "09/28/2016" } [1]=> array(5) { ["routeid"]=> int(3) ["academicyear"]=> string(4) "2016" ["current"]=> int(1) ["vehicleno"]=> string(9) "JK01S8764" ["dateofassignment"]=> string(10) "11/17/2016" } } ["HostelAlloted"]=> array(7) { ["Food Preferences"]=> string(4) "Both" ["Hostel"]=> object(MongoId)#25 (1) { ["$id"]=> string(24) "58138aee99fbade41e000031" } ["Floor"]=> string(7) "Floor_1" ["RoomNumber"]=> int(11) ["Approved"]=> string(3) "yes" ["Approved On"]=> object(MongoDate)#26 (2) { ["sec"]=> int(1472322600) ["usec"]=> int(0) } ["Academic Year"]=> string(4) "2016" } ["HostelAllotmentHistory"]=> array(1) { [0]=> array(7) { ["Food Preferences"]=> string(4) "Both" ["Hostel"]=> object(MongoId)#27 (1) { ["$id"]=> string(24) "58138aee99fbade41e000031" } ["Floor"]=> string(7) "Floor_1" ["RoomNumber"]=> int(11) ["Approved"]=> string(3) "yes" ["Approved On"]=> object(MongoDate)#28 (2) { ["sec"]=> int(1472322600) ["usec"]=> int(0) } ["Academic Year"]=> string(4) "2016" } } ["courseId"]=> object(MongoId)#29 (1) { ["$id"]=> string(24) "58131c7099fbad4c1d0001c2" } }

I am trying to bring those student on the beginning of array whose first name is brian and rest of students should at the bottom.
Now the above code place the students on the top of the array but the rest of the students are ommited/removed. I don't want them to be removed.
I am trying to tweak what code to write in else condition.
Please help!!!
Fill $arrayStudents before the loop otherwise only matches will be collected and unshifted.
Extend example of php.net/unshift
$add = array('big');
$queue = array(
array("orange"),
array("banana"),
array("apple1"),
array("raspberry")
);
array_unshift($queue, $add);
print_r($queue);
In your case: search for keys you want to unshift, the rest goes to the standard $list = array(/list of studends/):
$list = array();
$bringToTop = array('brian', 'elvis');
foreach($data as $item) {
if (/* in in the list to bring on top*/) {
$memory[] = $item;
} else {
$list[] = $item;
}
}
foreach($memory as $item) {
array_unshift($list, $item);
}
print_r($list);
Kind regards
Add $arrayStudents[] = $row; to your else scope. Here is a simple demo to illustrate it.
When matches add the element to the result from the start of array, unmatches add them from the end of the array.
I am obtaining a json object using the following:
$json = file_get_contents("url-here");
$data = json_decode($json, true);
//test
var_dump($data);
This gives me something like this:
array(2) { ["ok"]=> bool(true) ["result"]=> array(1) { [0]=> array(2)
{ ["update_id"]=> int(44893465) ["message"]=> array(5) {
["message_id"]=> int(16) ["from"]=> array(3) { ["id"]=> int(29595794)
["first_name"]=> string(3) "Bob" ["username"]=> string(14) "Bobo" }
["chat"]=> array(3) { ["id"]=> int(29595794) ["first_name"]=>
string(3) "Bob" ["username"]=> string(14) "Bobo" } ["date"]=>
int(1435354253) ["text"]=> string(7) "/q 3.33" } } } }
I would then like to add certain values into variables. For example I would like to extract username, text, message_id, etc
But no matter what I try my variables are empty:
//let's test it
echo "Username: " . $data[1][0]["username"];
//another test
echo $data->username;
Neither of these are working and my research has not helped me find a solution. I am stumped on this one.
Any pointers in the right direction would really be appreciated.
array(2) {
["ok"]=> bool(true)
["result"]=> array(1)
{
[0]=> array(2)
{
["update_id"]=> int(44893465)
["message"]=> array(5)
{
["message_id"]=> int(16)
["from"]=> array(3)
{
["id"]=> int(29595794)
["first_name"]=> string(3) "Bob"
["username"]=> string(14) "Bobo"
}
["chat"]=> array(3)
{
["id"]=> int(29595794)
["first_name"]=> string(3) "Bob"
["username"]=> string(14) "Bobo"
}
["date"]=> int(1435354253)
["text"]=> string(7) "/q 3.33"
}
}
}
}
You are using wrong array index. $data[1][0]["username"]; not exists.
$data["result"][0]["message"]["from"]["username"];
$data["result"][0]["message"]["chat"]["username"];
This will give you the proper username
$json = file_get_contents("url-here");
$data = json_decode($json, true);
//test
echo $data["result"][0]['message']['from']['username'];
output
Bobo
I got this array

}
}
I want to cut the where the id is 1411701737 so I tryed:
foreach($array as $arr => $sub_arr)
{
if $sub_arr['id'] == 1411701737
{
break;
}
}
I know I need to create a whole new array in the foreach, but isn't there maybe a build in function?
$arr_new = array(); //Define a new array
foreach($arr_old as $a) { //Loop through the old one
if($a['id'] === 1411701737) break; //If the value of id matches, leave the foreach loop
$arr_new[] = $a; //Else, copy this array to the new array
}
print_r($arr_new); //Print the new array
$new = array();
foreach($array as $k) {
if($k['id'] == 1411701737) break;
array_push($new, $k);
}
var_dump($new);
The answer by Mooseman is likely a faster way to do this since it does not rely on a PHP function call to place the array into the new array. However unless you are doing this on a set of arrays that is in the 100k+ it really won't matter.
Im new to json & php and I'm having some issues with json into php string
My json string looks like this
{"status":"OK","cards":
[{"id":100001,"name":"batman","image":11111,"size":75,"region_id":1,"locked":false,"status":"active","created_at":"2013-08-15T11:37:07Z"},
{"id":100002,"name":"superman","image":111111,"size":75,"region_id":1,"locked":false,"status":"active","created_at":"2013-08-15T12:30:09Z"},
{"id":100003,"name":"catwoman","image":1111111,"size":75,"region_id":1,"locked":false,"status":"active","created_at":"2013-08-15T12:39:42Z"},
{"id":100004,"name":"bane","image":1111111,"size":75,"region_id":1,"locked":false,"status":"active","created_at":"2013-09-08T12:56:04Z"}
]}
So Far i have created my string
$json_raw = '{"status":"OK","cards": [{"id":100001,"name": .....
Decoded the json
$arr = json_decode($json_raw, TRUE);
I var_dump($arr);
then it returns
array(2) { ["status"]=> string(2) "OK" ["cards"]=> array(4) { [0]=> array(8) { ["id"]=> int(100001) ["name"]=> string(6) "batman" ["image"]=> int(11111) ["size"]=> int(75) ["region_id"]=> int(1) ["locked"]=> bool(false) ["status"]=> string(6) "active" ["created_at"]=> string(20) "2013-08-15T11:37:07Z" } [1]=> array(8) { ["id"]=> int(100002) ["name"]=> string(8) "superman" ["image"]=> int(111111) ["size"]=> int(75) ["region_id"]=> int(1) ["locked"]=> bool(false) ["status"]=> string(6) "active" ["created_at"]=> string(20) "2013-08-15T12:30:09Z" } [2]=> array(8) { ["id"]=> int(100003) ["name"]=> string(8) "catwoman" ["image"]=> int(1111111) ["size"]=> int(75) ["region_id"]=> int(1) ["locked"]=> bool(false) ["status"]=> string(6) "active" ["created_at"]=> string(20) "2013-08-15T12:39:42Z" } [3]=> array(8) { ["id"]=> int(100004) ["name"]=> string(4) "bane" ["image"]=> int(1111111) ["size"]=> int(75) ["region_id"]=> int(1) ["locked"]=> bool(false) ["status"]=> string(6) "active" ["created_at"]=> string(20) "2013-09-08T12:56:04Z" } } }
Now all I want to do is be able to use this data
e.g if name = batman then
I know this is a stupid question but I am struggling :(
Thank in Advance
json_decode() with TRUE as second parameter gives you an associative array. You need to access the correct index to do what you want.
To list the complete associative array with nice formatting, you can do:
echo '<pre>', print_r($arr), '</pre>';
Now, to access the name in your array:
$man = $arr['cards'][0]['name'];
To check if it's Batman (yay!):
if( isset($man) && $man == 'batman' ) {
# code ...
}
For getting the name of all similar names:
$man = $json['cards']['0']['name'];
for ($i=0; $i < count($json['cards']); $i++) {
echo $json['cards'][$i]['name']."\n";
}
See it live!
when you got the array
$arr = json_decode($json_raw, TRUE);
then check if cards key exist
if(array_key_exists('cards', $arr)){
foreach($arr['cards'] as $key=>$val){
echo $key; ///name, id..
echo $val; /// batman,...
if($key == 'name' && $val =='batman'){
//-------do your stuff
}
}
}
Try with:
$cards = $arr['cards'];
foreach($cards as $card) {
if($card['name'] == 'batman') echo 'Hello batman!';
}
EDIT:
Ok, so this worked for me using code above, try it yourself if you want:
<?php
$json_raw = '{"status":"OK","cards":
[{"id":100001,"name":"batman","image":11111,"size":75,"region_id":1,"locked":false,"status":"active","created_at":"2013-08-15T11:37:07Z"},
{"id":100002,"name":"superman","image":111111,"size":75,"region_id":1,"locked":false,"status":"active","created_at":"2013-08-15T12:30:09Z"},
{"id":100003,"name":"catwoman","image":1111111,"size":75,"region_id":1,"locked":false,"status":"active","created_at":"2013-08-15T12:39:42Z"},
{"id":100004,"name":"bane","image":1111111,"size":75,"region_id":1,"locked":false,"status":"active","created_at":"2013-09-08T12:56:04Z"}
]}';
$arr = json_decode($json_raw, TRUE);
$cards = $arr['cards'];
foreach($cards as $card) {
if($card['name'] == 'batman') echo 'Hello batman!';
}
?>
