Question

我必须将表单值保存到PHP会话中，并希望保留所有表单值，直到表单提交：

我这样试过：

$pattern = '';
if(isset($_REQUEST['submit'])) :
   $s1 =  $_REQUEST['step1'];
   $s2 = $_REQUEST['step2'];
   $s3 = $_REQUEST['step3'];
   $s4 = $_REQUEST['step4'];
$pattern .= $s1.$s2.$s3;
$p_cat= $_REQUEST['p_cat'];

$_SESSION['mywine'] =  $pattern;
$_SESSION['quantity'] =  $_REQUEST['step4'];

if($p_cat == 'mixed')
$p_cat = 'red,white';
else $p_cat=  $_REQUEST['p_cat'];
endif;



 $my_wine = $_SESSION['mywine'];
 $qun = $_SESSION['quantity'];

         $args = array(
             'post_type' => 'product',
                 'product_cat' => $p_cat,
                   'posts_per_page' => 3,
                           'meta_query' => array(
                              array(
                               'key' => 'product_score_pattern',
                                'value' => $my_wine,
                                'compare' => '='
                                )
                               )
                             );

        $loop = new WP_Query( $args );
        if ( $loop->have_posts() ) {

            while ( $loop->have_posts() ) : $loop->the_post(); 

                 endwhile;
                endif;

此代码能够将数据保存到会话中，但是当我刷新页面时，会话值将为空。

我希望保持表格形式直到表单提交。这怎么可能？

您必须先致电public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.pelle); Intent intent = getIntent(); eEntreprise2 = intent.getStringExtra("eEntreprise"); eAdresse2 = intent.getStringExtra("eAdresse"); eIdVerificateur2 = intent.getStringExtra("eIdVerificateur"); eNomProprio2 = intent.getStringExtra("eNomProprio"); eAdresseProprio2 = intent.getStringExtra("eAdresseProprio"); eNomEntreprise2 = intent.getStringExtra("eNomEntreprise"); eAdresseEntreprise2 = intent.getStringExtra("eAdresseEntreprise"); eJourVerif2 = intent.getStringExtra("eJourVerif"); eMoisVerif2 = intent.getStringExtra("eMoisVerif"); eAnneeVerif2 = intent.getStringExtra("eAnneeVerif"); }才能分配或访问session_start()变量，如下所示。

$_SESSION

好的，你正在使用wordpress，它不允许创建会话..你需要参考这个

Wordpress session management

提交后将表单值存储到会话中并保存，直到表单再次提交：PHP
