PHP - 查询更改我的会话变量

时间：2015-08-30 01:27:36

标签： php variables session

以下代码可以使用一次。

加载页面时，数据会正确显示。但是，当我刷新页面时，我的所有会话变量都会发生变化，以反映从下面的sql查询中提取的数据。它只在我运行查询并在同一页面上显示会话变量时才会发生。如果我有一个没有另一个，它不会发生。我一直在寻找一个解决方案几个小时，但我无法解决这个问题。我是SQL和PHP的新手，请原谅我的无知。任何指导都非常感谢。

编辑更多信息.. 这段代码是通过jQuery加载的。我首先在表clients上开始使用一个查询来填充#chapter1-accountInfo。我后来想要显示在主帐户下注册的所有子代理商，并添加了下面的查询以填充.listTable。每当两者都完成时，它就会捏造我的会话变量。我尝试体验，将#chapter1-accountInfo的字段分配给会话变量暂时，看看是否只在表clients上运行一个查询就可以修复我的问题问题。它没有。这就是我在下面声明这么多会话变量的原因。

PHP brokerAccountInfo.php 

<?php session_start() ;

include ( 'database/sql_link.php' ) ;

$ID          = $_SESSION[ 'loginID'    ] ;
$companyName = $_SESSION[ 'company'    ] ;
$authority   = $_SESSION[ 'userLevel'  ] ;
$realName    = $_SESSION[ 'actualName' ] ;
$userName    = $_SESSION[ 'userName'   ] ;
$contact     = $_SESSION[ 'email'      ] ;

echo "

    <h2 class='chapterTitle'>
        Account Details
    </h2>

    <div class='chapter1' id='chapter1-accountInfo'>

        <p class='floatLeft'> Company Name: </p>
        <p class='floatRight'> $companyName </p>

        <br clear='both'>

        <p class='floatLeft'> Your Name: </p>
        <p class='floatRight'> $realName </p>

    </div> " ;

$query  = "    SELECT     *
               FROM       clients
               WHERE      companyName = '$companyName'
               AND        userLevel   = 'subBroker'
          " ;


$result = $db -> query( $query ) ;

if ( !$result = $db -> query($query) ) {
    die( ' There was an error running the query [ ' . $db -> error . ' ] ' ) ;
}

echo "
       <h2 class='chapterTitle'> Your Sub-Accounts </h2>

       <table  id='brokerSubBrokersTable'>
       <thead>
           <tr>
               <th> Company    </th>
               <th> Name       </th>
               <th> Login Name </th>
               <th> Email      </th>
           </tr>
       </thead>
       <tbody>
     " ;

while( $row = $result -> fetch_assoc() ) {

    $company     = $row[ 'companyName' ] ;
    $actualName  = $row[ 'actualName'  ] ;
    $loginName   = $row[ 'userName'    ] ;
    $email       = $row[ 'eMail'       ] ;

    echo "  <tr>
                 <td>  $company    </td>
                 <td>  $actualName </td>
                 <td>  $loginName  </td>
                 <td>  $email      </td>
            </tr> " ;
}
echo " </tbody>
       </table> " ;

我认为如果我分享其他代码会有所帮助，

JS - 这是我正在使用的加载功能 

$( '#navBrokeAccount' ).on( 'click' , function() {

        $( '#content' ).fadeOut( 'fast' ).hide() ;
        $( '#content' ).load( 'brokerAccount.php' , function() {

            $( '.chapter1' ).load( 'brokerAccountInfo.php' ) ;

        } ).delay( 500 ).fadeIn( 'slow' ) ;
 } ) ;

PHP - 这是会话的初始设置（同样，我不打算保留这么多会话变量）

<?php session_start() ;



if( !function_exists( 'hash_equals' ) )
{

    function hash_equals( $a , $b )
    {

        $ret   = strlen( $a ) ^ strlen( $b ) ;
        $ret  |= array_sum( unpack( "C*" , $a ^ $b ) ) ;

        return !$ret ;

    }

}




include( 'database/sql_link.php' ) ;

$user    = mysqli_real_escape_string( $db , $_GET[ 'uName' ] ) ;
$pass    = mysqli_real_escape_string( $db , $_GET[ 'pWord' ] ) ;
$query   = "
             SELECT  *
             FROM    clients
             WHERE   userName = '$user'
           " ;

$result = $db -> query( $query ) ;

if ( mysqli_num_rows( $result ) == 0 )
{

    echo "error" ;

}

else
{

    while ( $row  = $result -> fetch_assoc() ) {

        $userName    = $row[ 'userName'    ] ;
        $hash        = $row[ 'Pass_Word'   ] ;
        $companyName = $row[ 'companyName' ] ;
        $realName    = $row[ 'actualName'  ] ;
        $id          = $row[ 'ID'          ] ;

        $userLevel   = $row[ 'userLevel'   ] ;
        $email       = $row[ 'eMail'       ] ;

    }

    if ( hash_equals( $hash , crypt( $pass , $hash ) ) ) {

        $_SESSION[ 'loginID'    ] = $id          ;
        $_SESSION[ 'company'    ] = $companyName ;

所以我修好了..我想......

我仍然不知道为什么变量会发生变化。

当我在brokerSubBrokersTable.php中弄乱变量名时，它开始工作了。此文件中的某些变量由表中查询的数据填充为$_SESSION['']中设置的checkLogin.php变量之一

我的工作代码：

<强>的jQuery 

    $( '#content').load( 'brokerAccount.php' , function() {
        $.getJSON( 'brokerAccountInfo.php' , function( info ) {

            var companyInf = ( info.companyInf ) ;
            var nameInf    = ( info.nameInf    ) ;
            var levelInf   = ( info.levelInf   ) ;
            var activeInf  = ( info.activeInf  ) ;

            $ ( '#chapter1-accountInfo-company' ).text( companyInf ) ;
            $ ( '#chapter1-accountInfo-name'    ).text( nameInf    ) ;
            $ ( '#chapter1-accountInfo-level'   ).text( levelInf   ) ;
            $ ( '#chapter1-accountInfo-active'  ).text( activeInf  ) ;

            // This query is where the initial problem was.  Changed some variable names and it started working . .
            //
            $( '#chapter1-subBrokersList' ).load( 'brokerSubBrokersTable.php' ) ;

        } ) ; // End JSON function . .

    } ) ; // End .load function . .
