Question

我想通过会话发布$dataHeadArr值并在下一页中获取。

<?php 
if(isset($_POST["search"]))
{ $storename=$_POST["StoreName"];
    $dataHeadArr=$db->query("SELECT *FROM  `opening_stk`");?>

Answer 1

您可以在POST或SESSION数组中设置它，然后在下一页上检索它。对于前 -

$_POST['dataHeadArr']=$dataHeadArr;

Answer 2

存储......

$_SESSION['dataHeadArr'] = 'Whatever';

然后简单地检索..

if(isset($_SESSION['dataHeadArr'])){
    echo $_SESSION['dataHeadArr'];
}

确保调用session_start（）;在每页的顶部。

Answer 3

打开您发布的页面

<?php 
    if(isset($_POST["search"])){
        session_start(); 
        $storename=$_POST["StoreName"];
        $dataHeadArr=$db->query("SELECT * FROM  `opening_stk`");
        while($row=mysql_fetch_assoc($dataHeadArr)){
           $allRows[]=$row;
        }
        $_SESSION['dataHeadArr']=$allRows;
    }

?>

对于要检索变量put的页面

<?php
   session_start();
   $dataHeadArr=$_SESSION['dataHeadArr'];
   //This mysql result been parsed already, so you should be 
   //able to access values when you loop through it from here
   for($i=0;$i<count($dataHeadArr); $i++){
       echo "Printing row ".$i."</br>";
       foreach($dataHeadArr[$i] as $key=>$item){ 
            //Prints out all value for the row
            echo $item[$key]."</br>";
       }
       echo "</br>";
   }
?>
