Bonjour,
Dans mon code je defini une variable $yTasks qui contien un array.
quand je fais un var_dump de cette variable tout marche mais quand je veut l'utiliser juste plus bas dans un foreach ces erreurs sont retournées
Warning: Undefined variable $ytasks in D:\Xammp\htdocs\my_php_projects\todo_list\index.php on line 66
Warning: foreach() argument must be of type array|object, null given in D:\Xammp\htdocs\my_php_projects\todo_list\index.php on line 66
voici mon code php:
$yTasks = array_filter($allTasks,function($e){
return $e["date"] > $e['beforeYesterday'] AND $e["date"] < $e['today'];
});
var_dump($yTasks);
$new_y_tasks=array();
foreach( $ytasks as $key => $task ) {
if($task['parentId']===0){
array_push($new_y_tasks,$task);
}
}
var_dump($new_y_tasks);
Et mon code en entier si besoin :
<?php
if(!isset($_COOKIE['connectionCookie'])){
header('location:/my_php_projects/todo_list/login_page.php');
}
include "db.php";
$mail=$_COOKIE['connectionCookie'];
$date=DateTime::createFromFormat('d-m-Y H:i:s', date('d-m-Y').' 00:00:00')->getTimestamp();
$beforeYesterdayTimestamp=$date-(3600*24*2);
$yesterdayTimestamp=$date-(3600*24);
$todayTimestamp=$date;
$tomorowTimestamp=$date+(3600*24);
// delete old tasks
$delSQL="DELETE FROM tasks WHERE mail='$mail' AND date < '$yesterdayTimestamp' ";
$delReq= $db->prepare($delSQL);
$delReq->execute();
// moove in today yesterday's tasks which aren't checked
$getTasksToMooveSQL="SELECT id FROM tasks WHERE date = $yesterdayTimestamp AND checked = 0";
$getTasksToMooveReq= $db->prepare($getTasksToMooveSQL);
$getTasksToMooveReq->execute();
if($getTasksToMooveReq->rowCount()>0){
$ids=$getTasksToMooveReq->fetchAll();
$newIds=array();
foreach ($ids as $id) {
array_push($newIds,$id['id']);
}
$mooveSQL="UPDATE tasks SET date = $todayTimestamp WHERE ";
foreach ($newIds as $key => $id) {
$mooveSQL=$mooveSQL." id = ".$id." OR parentId = ".$id;
if($key < count($newIds)-1){
$mooveSQL=$mooveSQL." OR";
}
}
$mooveReq= $db->prepare($mooveSQL);
$mooveReq->execute();
}
$allTasksSQL="SELECT * FROM tasks WHERE mail='$mail' ORDER BY id";
$allTasksReq=$db->prepare($allTasksSQL);
$allTasksReq->execute();
$allTasks = $allTasksReq->fetchAll();
// add day to tasks
foreach ($allTasks as $key => $task) {
$allTasks[$key]['beforeYesterday']=$beforeYesterdayTimestamp;
$allTasks[$key]['yesterday']=$yesterdayTimestamp;
$allTasks[$key]['today']=$todayTimestamp;
$allTasks[$key]['tomorow']=$tomorowTimestamp;
}
// get tasks by day
$yTasks = array_filter($allTasks,function($e){
return $e["date"] > $e['beforeYesterday'] AND $e["date"] < $e['today'];
});
var_dump($yTasks);
$new_y_tasks=array();
foreach( $ytasks as $key => $task ) {
if($task['parentId']===0){
array_push($new_y_tasks,$task);
}
}
var_dump($new_y_tasks);
$todTasks = array_filter($allTasks,function($e){
return $e["date"] > $e['yesterday'] AND $e["date"] < $e['tomorow'];
});
$tomTasks = array_filter($allTasks,function($e){
return $e["date"] > $e['today'] ;
});
function displayTasks($tasks){
foreach ($tasks as $task) {
$value=$task['value'];
$id=$task['id'];
$checked=$task['checked']===1?'checked':'';
echo "
<div class='task $checked' data-id='$id'>
<div class='content'>
<input type='checkbox' $checked id='taskCheck$id' />
<label for='taskCheck$id'>$value</label>
<button class='addChild'>+</button>
<button class='delete'>X</button>
</div>
</div>
";
}
}

Oh merci je n'avais pas vu
Sinon j'ai un autre problème,
quand j'exécute ce code:
$yTasks = array_filter($allTasks,function($e){
return $e["date"] > $beforeYesterdayTimestamp AND $e["date"] < $todayTimestamp;
});
j'ai ces erreurs:
Warning: Undefined variable $beforeYesterdayTimestamp in D:\Xammp\htdocs\my_php_projects\todo_list\index.php on line 62 Warning: Undefined variable $todayTimestamp in D:\Xammp\htdocs\my_php_projects\todo_list\index.php on line 62
alors que j'ai défini ces variables avant comme ça :
$date=DateTime::createFromFormat('d-m-Y H:i:s', date('d-m-Y').' 00:00:00')->getTimestamp();
$beforeYesterdayTimestamp=$date-(3600*24*2);
$yesterdayTimestamp=$date-(3600*24);
$todayTimestamp=$date;
$tomorowTimestamp=$date+(3600*24);
Savez vous d'où viens le problème ?
