I have 1 array:
$meta_array = array(
'lot',
'floor',
'block'
);
How can I convert the above array to show
'lot' => $_POST['lot'], 'floor' => $_POST['floor']
so I can update_post_meta($new, 'number' , $meta_array) like this.
I am trying to save some KBs as my form php size is getting rather large.
Thank you for your advice.
FINALLY - I DID THIS
$new_meta = array();
foreach($meta_array as $val){
if (isset($_POST[$val])) {
$new_meta[$val] = sanitize_array_text_field($_POST[$val]);
}
}
update_post_meta($new, 'property', $new_meta);
use :
$posted = array_combine ($meta_array, $_POST);
You will get :
Array(
[lot] => $_POST['lot'],
[floor] => $_POST['floor'],
[block] => $_POST['block']
)
Use a foreach loop:
$meta_array = array('lot', 'floor', 'block');
$another_array = array();
foreach($meta_array as $val){
$another_array[$val] = $_POST[$val];
}
You could also do:
if(isset($_POST['lot']))
$meta_array['lot'] = $_POST['lot'];
if(isset($_POST['floor']))
$meta_array['floor'] = $_POST['floor'];
if(isset($_POST['block']))
$meta_array['block'] = $_POST['block'];
Using isset() is a little safer.

I have this array in PHP
$fields = array(
0 => array(
'field1' => 'something1',
'field2' => 'something2'
)
)
And I need it to look like this
$fields = array(
'fields1' => 'something1',
'fields2' => 'something2'
)
What function code can I use to get rid of the 0 index in the example?
You can loop through like this...
Create new array
$newArray = [];
Then loop through
foreach($fields as $field){
if(is_array($field)){
foreach($field as $key => $value){
$newArray[$key] = $value;
}
}
}
just take the '0' element from fields:
$fields=$fields[0];
Simple
$fields = reset($fields);
Or
$fields = array_shift($fields);
Create an array, loop through $fields, and merge whatever items are there with the created array.
$final_array = array();
foreach ($fields as $field)
{
$final_array = array_merge($final_array, $field);
}
$fields = $final_array;
This will be able to handle any number of items in either level of the array and compact them into a one-level array.
$it = new RecursiveIteratorIterator(new RecursiveArrayIterator($data)); $list = iterator_to_array($it,false);
Use this to get ride of any extra levels.
Will gives you what you want
first array like this
$zones_array1 = array();
$zones_array1[] = array('id' => 'Alabama', 'text' => 'Alabama');
$zones_array1[] = array('id' => 'Alaska', 'text' => 'Alaska');
$zones_array1[] = array('id' => 'Arizona', 'text' => 'Arizona');
$zones_array1[] = array('id' => 'Arkansas', 'text' => 'Arkansas');
second array like this
$zones_array2 = array();
$zones_array2[] = array('id' => 'Alaska', 'text' => 'Alaska');
$zones_array2[] = array('id' => 'Arizona', 'text' => 'Arizona');
i want filter these two array and i want final result as array like this
first array like this
$zones_array3 = array();
$zones_array3[] = array('id' => 'Alabama', 'text' => 'Alabama');
$zones_array3[] = array('id' => 'Arkansas', 'text' => 'Arkansas');
please help me
You can use php 'in_array' to check weather an element exists inside other array or not. In you case the array is multidimensional so stored all the id's inside a newly created array and then compared the given array with that.
$check_array = array();
foreach ($zones_array1 as $arr1){
$check_array[] = $arr1['id'];
}
$zones_array3 = array();
foreach ($zones_array2 as $arr2){
if (!in_array($arr2['id'], $check_array))
{
$zones_array3[] = $arr2;
}
}
echo '<pre>';
print_r($zones_array3);
Simply try:
function udiffCompare($a, $b)
{
return $a['id'] == $b['id'] ? 0 : -1;
}
$arrdiff = array_udiff($zones_array1, $zones_array2, 'udiffCompare');
echo '<pre>';
print_r($arrdiff);
array_udiff() compares each element of the first array-argument against all the elements of the second array-argument using the provided callback function. If the callback returns zero for any of the comparisons then the element of the array in the first argument will not be present in the returned array of the function.
You will try it :
function unique_multidim_array($array, $key){
$temp_array = array();
$i = 0;
$key_array = array();
foreach($array as $val){
if(!in_array($val[$key],$key_array)){
$key_array[$i] = $val[$key];
$temp_array[$i] = $val;
}
$i++;
}
return $temp_array;
}
$zones_array1 = array_merge($zones_array2, $zones_array3);
$zones_array1 = unique_multidim_array($zones_array1, 'id');
print_r($zones_array1);
Please try this
array_push($zones_array1,$zones_array2);
print_r(array_unique($zones_array1));
I am not sure.
Hi I'm a newbie of FuelPHP. I'm makin' a demo use ACL. I have fetched all roles from database with format as the code below
$data = array(
array('admin'=>array(
'none' => array(
'crudform' => array('create','index')
)
)),
array('admin'=>array(
'none' => array(
'cruddept' => array('create','view')
)
)),
);
And now I want to convert that array to format as
$data = array(
'admin' => array(
'none'=>array(
'crudform' => array(
'create',
'index'
),
'cruddept'=>array(
'create',
'view'
)
)
)
)
How I can do that ?
After you retreive your data from database, you can convert your array using a function just like this one
function change_array($data)
{
$result = array('admin' => array('none' => array()));
foreach ($data as $key => $value)
foreach ($data[$key]['admin']['none'] as $key_child => $value_child)
$result['admin']['none'][$key_child] = $value_child;
return $result;
}
All you need to do, is to use it like this
$data = change_array($data);
Thanks Mr Khalid, your idea has provide a way for me how to resolve my solution. I have found the way to build array as I want. This is my code
function build_role_array($roles){
$final = array();
foreach($roles as $row){
foreach($row as $role=>$value){
if(!isset($final[$role])){
$final[$role] = array();
}
foreach($value as $module=>$area){
if(!isset($final[$role][$module])){
$final[$role][$module] = array();
}
foreach($area as $controller=>$rights){
$final[$role][$module][$controller] = $rights;
}
}
}
}
return $final;
}
Thanks for support
Hello how can i convert string to array but it should be in nested format. like i show in the example.
first i tried to explode "/" then i try static variable in foreach loop.. but no luck.
i'm beginner & still confused how to do this..
FROM
$str = 'first/second/third';
To
array(
'first' => array(
'second' => array(
'third' => array(
)
)
)
);
Apply cleverness :p
$keys = explode("/",$str);
$result = array();
$ref = &$result;
foreach($keys as $key) {
$ref[$key] = array();
$ref = &$ref[$key];
}
unset($ref); // delete the reference
I have an array that looks like this:
array
0 =>
array
'title' => string 'Ireland - Wikipedia, the free encyclopedia'
'url' => string 'http://en.wikipedia.org/wiki/Ireland'
1 =>
array
'title' => string 'Ireland's home for accommodation, activities.'
'url' => string 'http://www.ireland.com/'
that I want to add a score of 0 to each element. I thought this simple foreach loop would do the trick but...well....it doesn't :/
public function setScore($result)
{
foreach($result as $key)
{
$key = array('title', 'url', 'score' => 0);
}
return $result;
}
Can someone help me out?
Thanks
foreach works on a copy of the array. You can modify $key all you want, it's not going to reflect on the original array.
You can use $key by reference though, then it'll work as expected:
foreach ($result as &$value) {
$value['score'] = 0;
}
Manual entry: http://php.net/manual/en/control-structures.foreach.php
You create a new array here and do nothing with it:
foreach($result as $key){
$key = array('title', 'url', 'score' => 0);
}
What you want to do is to modify a reference to existing one:
foreach($result as &$key){ # Note the '&' here
$key['score'] = 0;
}
Although deceze is right, you can also do this using array_walk(), like this:
array_walk( $result, function( &$el) { $el['score'] = 0; });
Here's an example of how to accomplish this.
$array = array( array( 'title' => "Ireland - Wikipedia, the free encyclopedia", 'url' => "http://en.wikipedia.org/wiki/Ireland"), array( 'title' => "Ireland's home for accommodation, activities.", 'url' => "http://www.ireland.com/" ) );
function setScore( $result )
{
foreach( $result as &$element )
{
$element['score'] = 0;
}
return $result;
}
$array = setScore( $array );
print_r( $array );
You could also do:
function setScore( &$result )
{...}
and then just:
setScore( $array );
