I have form (display.php) that will get multiple selected option from user. Then this selected option will be formatted to another page (page.php). The problem occur when I try to display those multiple selected option. The array index are changing into string [name]!
Array ( [0] => 3204120006 [1] => 3204120011 [2] => 3204120010 [3] => 3204120009 )
Array ( [name] => BIRU ) Array ( [name] => BOJONG ) Array ( [name] => MAJAKERTA ) Array ( [name] => MAJALAYA )
Here the code of above display.
<?php
if (isset($_POST["desas"])) {
$ddes=$_POST["desas"];
print_r ($ddes);
foreach ( $ddes as $iddesa ) {
$namadesa=mysql_query("SELECT name FROM villages WHERE id='$iddesa' ");
if ($namadesa) {
$datadesa = mysql_fetch_assoc($namadesa);
print_r($datadesa);
}
} else
$datadesa="";
}
?>
My question is how to change ([name]=>BIRU),([name]=>BOJONG) into index ([0]=>BIRU),([1]=>BOJONG) etc on those array? or something missing in mysql fetch?
you can use array_values. reference: https://secure.php.net/manual/en/function.array-values.php
$datadesa = array_values(array_values);

When I use the code below:
print_r($jsoni);
$badge_url = "http://api.steampowered.com/ISteamUserStats/GetGlobalAchievementPercentagesForApp/v0002/?gameid=841370%3Fkey&steamids=76561198108211948&fbclid=IwAR0B4wUlosbqFElHBJw-AkLwb3mGsv42xKdtrEAarDmD97Ur3AprrkW4tCk";
$jsoni = json_decode(file_get_contents($badge_url), true);
I get the following as a result:
Array
(
[achievementpercentages] => Array
(
[achievements] => Array
(
[0] => Array
(
[name] => GAME_GREEN_LIGHT
[percent] => 70.9000015259
)
[1] => Array
(
[name] => CAREER_EARN_BADGE
[percent] => 62.2999992371
)
How can I get it so that it only shows the name and the percentage?
print_r($jsoni['achievementpercentages']['achievements'])
You could loop through the decoded data to create an associative array with the achievement names as keys and the percentages as values:
$achievements = [];
foreach($jsoni['achievementpercentages']['achievements'] as $achievement)
$achievements[$achievement['name']] = $achievement['percent'];
Which outputs:
Array
(
[GAME_GREEN_LIGHT] => 70.9000015259,
[CAREER_EARN_BADGE] => 62.2999992371
)
So im now using the following code.
<?php
$achievements = [];
foreach($jsoni['achievementpercentages']['achievements'] as $achievement)
$achievements[$achievement['name']] = $achievement['percent'];
print_r($achievements);
?>
wich results in
Array ( [GAME_GREEN_LIGHT] => 70.9000015259 [CAREER_EARN_BADGE] => 62.2999992371
how do i get it to show a list from top to bottom instead of in a cluster of text?
Thanks for the help!
So I want to delete an array element from a JSON array based on an id in a sub-array. I know it sounds weird. Here's an example of the array. I want to delete the entire array [0] based on the [dealer][id] array where the [id] = 20220 in this example.
Array
(
[results] => Array
(
[offset] => 1
[length] => 15
[data] => Array
(
[0] => Array
(
[dealer] => Array
(
[id] => 20220
[name] => apple
)
)
)
)
}
In reality there are a lot more elements in the [results] array. I'm not sure how to go about it.
Any help is greatly appreciated!
Loop thru data key first then check if dealer id matches the searched id
$id = 20220;
foreach ($array['results']['data'] as $key => $value) {
if ($value['dealer']['id'] == $id) {
unset($array['results']['data'][$key]);
}
}
use array_filter,
$array['results']['data'] = array_filter($array['results']['data'], function($v){return $v['dealer']['id'] != 20220;});
I'm using a form where the pair of inputs can be added per automatic. One store value in select and the other as input
After submit I receive the values in array and I need to associate them together. So all key values [0] belongs together and all [1] and so on.
Array
(
[issue] => Array
(
[0] => 2
[1] => 3
)
[qty] => Array
(
[0] => 1
[1] => 2
)
)
How can I do this using PHP?
Just use a simple foreach loop.
$combined = array();
foreach ($_POST["issue"] as $k=>$v) {
$combined[$k] = array($_POST["issue"][$k], $_POST["qty"][$k]);
}
print_r($combined);
I have a multi-dimensional array (There is more than one item in "data" but i'm just showing one for this question):
Array
(
[data] => Array
(
[0] => Array
(
[to] => Array
(
[data] => Array
(
[0] => Array
(
[name] => fake name
[id] => 668071477234
)
[1] => Array
(
[name] => fake name
[id] => 1345556711
)
)
)
[updated_time] => 2012-12-24T23:46:26+0000
[id] => 327424994013537
)
)
)
I am trying to loop thru the array and determine if the id matches a variable sent from $_REQUEST, and if it does, I only want to return the "updated_time" value of the iteration.
Here's what I have but the date is always wrong, and doesn't match the proper iteration:
foreach($userOutbox['data'] as $outbox){
foreach($outbox['to']['data'] as $user){
if($user['id'] == $_REQUEST['facebook_id']){
$last_message_date = $outbox['updated_time'];
}
}
}
It's late and my eyes and brain are not helping me. Can anyone give me any direction?
Here's the solution that worked for me, just added break 2; Thanks for your help:
foreach($userOutbox['data'] as $outbox){
foreach($outbox['to']['data'] as $user){
if($user['id'] == $_REQUEST['facebook_id']){
$last_message_date = $outbox['updated_time'];
break 2;
}
}
}
i retrieved data from mysql table in php
$array2=array(); while($q1= mysql_fetch_assoc($result))
{ print_r($q1);
$array2[]= $q['user_id'];
}
the print_r($q1) will output this Array ( [user_id] => 1 ) Array ( [user_id] => 2 ) Array ( [user_id] => 4 ) .
Now i want to assign these values into another array i.e
$array2[]=$q['user_id']; but when i echo $array2 this gives me result otherthan $print_r($q) i.e
Array ( [0] => [1] => [2] => )
my question is how can i get the value of [user_id]=>4 from this array
$q is different from $q1..
You need:
$array2[]= $q1['user_id'];
It should actually be throwing a warning about $q['user_id'] not being defined. Do you have error reporting turned on?
