I need a proper JSON file with "geo_langitude", "geo_latitude", "adress" & "url" values
I have wp database with post_meta "property" - "geo_langitude" "geo_latitude" & "address" in there.
my file is smth like that
<?php
function return_markers($count) {
$query = new WP_Query('post_type=property&posts_per_page=-1&orderby=menu_order&order=DESC&post_status=publish');
$array = array();
$i = 0;
for ($i = 0; $i< $count; $i++) {
$elem = array(
't' => 'string '.$i,
'x' => get_post_meta($post->ID,'geo_latitude',true),
'y' => get_post_meta($post->ID,'geo_longitude',true),
'z' => $i
);
$array[] = $elem;
}
echo json_encode($elem);
};
return_markers($i);
?>
It's my first time using JSON so I have troubles and I don't know where. =(
with random markers work perfectly:
<?php
function return_markers($count) {
$array = array ();
for ($i = 0; $i< $count; $i++) {
$elem = array(
't' => 'string '.$i,
'x' => 23 + (rand ( 0 , 10000 ) / 10000) * 5,
'y' => 56.2 + (rand ( 0 , 10000 ) / 10000) * 0.8,
'url' => '#map_redirect_'.$i,
'z' => $i
);
$array[] = $elem;
}
echo json_encode($array);
};
return_markers(23);
?>

I'm Getting some arrays from some wordpress custom fields:
$content = array(get_post_meta($postId, 'content'));
$media = array(get_post_meta($postId, 'media'));
$yt = array(get_post_meta($postId, 'youtube'));
I then need to have it printing in sequence, like:
media
content
LInk
Embed
And repeat the sequence for each value
media
content
LInk
Embed
For the sequence I'd use this:
echo '<ul>';
for ($i = 0; $i < count($all_array['media']); $i++) {
for ($j = 0; $j < count($all_array['content']); $j++) {
for ($k = 0; $k < count($all_array['youtube']); $k++) {
echo '<li>media->' . $all_array['media'][$i] . '</li>';
echo '<li>content->' . $all_array['content'][$j] . '</li>';
echo '<li>link->' . $all_array['link'][$k] . '</li>';
}
}
}
echo '</ul>';
But I'm doing something wrong with the merging of the 3 fields as if I do a var_dump before to run the for bit, like
echo '<pre>' . var_export($all_array, true) . '</pre>';
Then this is what I get and I cannot iterate as I wish:
array (
0 =>
array (
0 =>
array (
0 => '
brother
',
1 => '
Lorem
',
2 => '
End it
',
),
1 =>
array (
0 => '337',
1 => '339',
),
2 =>
array (
0 => 'https://www.youtube.com/watch?v=94q6fzbJUfg',
),
),
)
Literally the layout in html that I'm looking for is:
image
content
link
image
content
link
...
UPDATE
This how I am merging the arrays:
foreach ( $content as $idx => $val ) {
$all_array[] = [ $val, $media[$idx], $yt[$idx] ];
}
This is the associative array how it looks like:
Content:
array (
0 =>
array (
0 => '
brother
',
1 => '
Lorem
',
2 => '
End it
',
),
)
Media
array (
0 =>
array (
0 => '337',
1 => '339',
),
)
Youtube
array (
0 =>
array (
0 => 'https://www.youtube.com/watch?v=94q6fzbJUfg',
),
)
The way I've resolved it is first I calculate the tot. items within each array, then I get the array with max items and loop and add the items in sequence:
//GET CUSTOM FIELDS
$content = get_post_meta($post_to_edit->ID, 'content', false);
$media = get_post_meta($post_to_edit->ID, 'media', false);
$yt = get_post_meta($post_to_edit->ID, 'youtube', false);
$max = max(count($content), count($media), count($yt));
$combined = [];
//
// CREATE CUSTOM FIELDS UNIQUE ARRAY
for($i = 0; $i <= $max; $i++) {
if(isset($media[$i])) {
$combined[] = ["type" => "media", "value" => $media[$i]];
}
if(isset($content[$i])) {
$combined[] = ["type" => "content", "value" => $content[$i]];
}
if(isset($yt[$i])) {
$combined[] = ["type" => "youtube", "value" => $yt[$i]];
}
}
Finally I can loop:
foreach ($combined as $key => $val) {
if($val['type'] === "media") {
...
}
if($val['type'] === "content") {
...
You don't need to merge the arrays together. It will work fine in separate arrays. However, your for loops don't have the right logic. Try:
for ($i = 0; $i < count($media); $i++) {
for ($j = 0; $j < count($media[$i]); $j++) {
echo '<li>media->' . $media[$i][$j] . '</li>';
}
for ($j = 0; $j < count($content[$i]); $j++) {
echo '<li>content->' . $content[$i][$j] . '</li>';
}
for ($j = 0; $j < count($youtube[$i]); $j++) {
echo '<li>link->' . $youtube[$i][$j] . '</li>';
}
}
I have a already defined array, containing values just like the one below:
$arr = ['a','b','c'];
How could one add the following using PHP?
$arr = [
'a' => 10,
'b' => 5,
'c' => 21
]
I have tried:
$arr['a'] = 10 but it throws the error: Undefined index: a
I am surely that I do a stupid mistake.. could someone open my eyes?
Full code below:
$finishes = []; //define array to hold finish types
foreach ($projectstages as $stage) {
if ($stage->finish_type) {
if(!in_array($stage->finish_type, $finishes)){
array_push($finishes, $stage->finish_type);
}
}
}
foreach ($projectunits as $unit) {
$data[$i] = [
'id' => $unit->id,
'project_name' => $unit->project_name,
'block_title' => $unit->block_title,
'unit' => $unit->unit,
'core' => $unit->core,
'floor' => $unit->floor,
'unit_type' => $unit->unit_type,
'tenure_type' => $unit->tenure_type,
'floors' => $unit->unit_floors,
'weelchair' => $unit->weelchair,
'dual_aspect' => $unit->dual_aspect
];
$st = array();
$bs = '';
foreach ($projectstages as $stage) {
$projectmeasure = ProjectMeasure::select('measure')
->where('project_id',$this->projectId)
->where('build_stage_id', $stage->id)
->where('unit_id', $unit->id)
->where('block_id', $unit->block_id)
->where('build_stage_type_id', $stage->build_stage_type_id)
->first();
$st += [
'BST-'.$stage->build_stage_type_id => ($projectmeasure ? $projectmeasure->measure : '0')
];
if (($stage->is_square_meter == 0) && ($stage->is_draft == 0)) {
$height = ($stage->height_override == 0 ? $unit->gross_floor_height : $stage->height_override); //08.14.20: override default height if build stage type has it's own custom height
$st += [
'BST-sqm-'.$stage->build_stage_type_id => ($projectmeasure ? $projectmeasure->measure * $height: '0')
];
if ($stage->finish_type) {
$finishes[$stage->finish_type] += ($projectmeasure ? $projectmeasure->measure * $height: '0') * ($stage->both_side ? 2 : 1); //error is thrown at this line
}
} else {
if ($stage->finish_type) {
$finishes[$stage->finish_type] += ($projectmeasure ? $projectmeasure->measure : '0');
}
}
}
$data[$i] = array_merge($data[$i], $st);
$data[$i] = array_merge($data[$i], $finishes[$stage->finish_type]);
$i++;
}
The above code is used as is and the array $finishes is the one from the first example, called $arr
You're using += in your real code instead of =. That tries to do maths to add to an existing value, whereas = can just assign a new index with that value if it doesn't exist.
+= can't do maths to add a number to nothing. You need to check first if the index exists yet. If it doesn't exist, then assign it with an initial value. If it already exists with a value, then you can add the new value to the existing value.
If you want to convert the array of strings to a collection of keys (elements) and values (integers), you can try the following:
$arr = ['a','b','c'];
$newVals = [10, 5, 21];
function convertArr($arr, $newVals){
if(count($arr) == count($newVals)){
$len = count($arr);
for($i = 0; $i < $len; $i++){
$temp = $arr[$i];
$arr[$temp] = $newVals[$i];
unset($arr[$i]);
}
}
return $arr;
}
print_r(convertArr($arr, $newVals));
Output:
Array ( [a] => 10 [b] => 5 [c] => 21 )
I am generating test data for use in my frontend and I want to generate ages. Currently I am generating age between 18 and 100 using rand(1,100) like this:
require_once 'vendor/autoload.php';
$faker = Faker\Factory::create();
$superstars = array("Adam Cole","Finn Balor","Pete Dunne","Jordan Devlin","Noam Dar");
$fan_favourite_superstar_name = $superstars[ mt_rand( 0, count($superstars) -1 ) ];
$cities = array("London","Manchester","Leeds","Bristol");
$fan_location = $cities[ mt_rand( 0, count($cities) -1 ) ];
$the_models = array("Iphone","Nokia","Huawei","Samsung");
$fan_phone_model = $the_models[ mt_rand( 0, count($the_models) -1 ) ];
$array = Array (
"0" => Array (
"id" => uniqid(),
"fan_favourite_superstar_name" => $fan_favourite_superstar_name,
"fan_location" => $fan_location,
"fan_phone_model" => $fan_phone_model,
"fan_name" => $faker->name,
"fan_age" => rand(18,100),
"fan_comments" => $faker->text,
"fan_picture" => rand(1,500),
"last_updated" => time() + rand(1,1000),
),
However, I would like my ages to repeat although not completely. Is there a weak randomness generator apart from rand that can ensure that the an ages generated randomly repeat themselves n times?.
Here is a function just to show my suggestion of solution:
function getAge($start = 18, $end = 100, $repeat = 20){
$result = null;
static $ages = array();
if ( empty($ages) ) {
for ($i= $start; $i <= $end; $i++) {
for($j = 0; $j < $repeat; $j++)
$ages[] = $i;
}
}
$index = rand(0, count($ages));
$result = $ages[ $index ];
unset($ages[ $index ]);
$ages = array_values($ages);
return $result;
}
Basically, what I'm trying to do is loop inside a loop and in arrays. I have no idea how to do it (that's why I'm here) and I've been testing many things.
As it sounds very confused I write down the code how it would be, but clearly that's not correct.
This below is what I've tried.
$whatever->insertOne(
['name' => 'whatever',
'data' => array(
for ($i = 0 ; $i < 50 ; $i++) { // <-first loop
'something' => array(
for ($j = 0 ; $j < 50 ; $j++) { // <-second loop
'somevalue' => array(
'date' => $date,
'value' => mt_rand(0,200)
)
}
)
}
)
]);
Try this out:
$data = array();
for ($j = 0 ; $j < 50 ; $j++) {
for ($i = 0 ; $i < 50 ; $i++) {
$data[$j]['something'][$i]['date'] => $date;
$data[$j]['something'][$i]['value'] => mt_rand(0,200);
}
}
$whatever->insertOne(['name' => 'whatever','data' => $data]);
Loop need to be outside to create final array. Don't add loop inside an array.
You probably need something like below:-
$data = ['name' => 'whatever'];
for ($i = 0 ; $i < 50 ; $i++) {
for ($j = 0 ; $j < 50 ; $j++) {
$data[$i]['something'][$j]=['somevalue' => array('date' => $date,'value' => mt_rand(0,200));
}
}
$whatever->insertOne($data);
Note:- you can print your array before insertOne() to check that you are getting array of correct format or some more manipulation needed.Thanks
I want to create an array in a for-loop so i can adjust the size ($i) of the array.
I've tried this:
$array = array();
for($i = 1; $i <= 5; $i++) {
array_push($array,
$i => array(
"id" => "",
"option" => ""
)
);
}
But I get the following error:
Parse error: syntax error, unexpected '=>' (T_DOUBLE_ARROW) in ...
I'v also tried to make it a string by doing $i."" on line 4 but that doesn't seem to work either. Does anyone know why?
More idiomatic would be:
$array = array();
for($i = 1; $i <= 5; $i++) {
$array[$i] = array(
"id" => "",
"option" => "") ;
}
However note that this will give you array indexes from 1-5. Arrays are usually indexed from 0:
$array = array();
for($i = 0; $i < 5; $i++) {
$array[$i] = array(
"id" => "",
"option" => "") ;
}
But this can be done without specifying the key:
$array = array();
for($i = 1; $i <= 5; $i++) {
$array[] = array(
"id" => "",
"option" => "") ;
}
try this:
$array = array();
for($i = 1; $i <= 5; $i++) {
$array[$i] = array(
"id" => "",
"option" => ""
);
}
Remove the $i =>
$array = array();
for($i = 1; $i <= 5; $i++) {
array_push($array, array(
"id" => "",
"option" => ""
)
);
}
