如何在PHP中為SQL查詢結果創建會話

Question

我想為記錄tag_id創建會話，這是我的sql代碼，請幫助我如何為該值創建會話。

<?php

  $sql_tagid=mysql_query("SELECT * FROM tag_new WHERE EMAIL_ID='$sessionemail' AND  CUST_ID='$id'") or die(mysql_error());
while($tagid=mysql_fetch_array($sql_tagid)){
    echo $tagid['tag_id'];
}
?>

Answer 1

<?php

  session_start();  // To assign a session variable you have to start the session

  $sql_tagid=mysql_query("SELECT * FROM tag_new WHERE EMAIL_ID='$sessionemail' AND  CUST_ID='$id'") or die(mysql_error());

  while($tagid=mysql_fetch_array($sql_tagid))
  {

       $_SESSION['tag_id'] = $tagid['tag_id']; // assign tag_id value to session variable

       echo $tagid['tag_id'];
  }
?>

為了獲得另一頁上會話的值，請說page1.php，那么您必須做：-

page1.php中

<?php

 session_start();

 echo $_SESSION['tag_id'];


?>

Answer 2

$_SESSION['tag'] = $tagid['tag_id']

Answer 3

首先，您需要開始會議

session_start();

之后，將變量添加到會話

$_SESSION['tag'] = $tag['tag_id']

之后，您可以按打印會話進行檢查

print_r($_SESSION); 您是否重視會話

Answer 4

嘗試此操作，如果您具有多個標記ID，則如果只有一個$_SESSION['tag_id'] ，則使用它$_SESSION['tag_id'][] $_SESSION['tag_id']

session_start();

while($tagid=mysql_fetch_array($sql_tagid)){
  $_SESSION['tag_id'][] = $tagid['tag_id'];
}

var_dump($_SESSION['tag_id']);
