php - 関数値を $_POST に取得する方法

Question

したがって、フォームの状態ドロップダウン選択であるこの関数を取得して、別のファイルで $_POST を使用して送信されたときに選択されたものの値を取得しようとしています。 ' 送信されるパラメーター。

これが私のコードです

<?php
    function state_select ($name,$full_state,$selected = '') {

  $state_list = array("AL|Alabama","AK|Alaska","AZ|Arizona", "AR|Arkansas", "CA|California", "CO|Colorado", "CT|Connecticut", "DE|Delaware", "DC|Washington D.C.", "FL|Florida", "GA|Georgia", "HI|Hawaii", "ID|Idaho", "IL|Illinois", "IN|Indiana", "IA|Iowa", "KS|Kansas", "KY|Kentucky", "LA|Louisiana", "ME|Maine", "MD|Maryland", "MA|Massachusetts", "MI|Michigan", "MN|Minnesota", "MS|Mississippi", "MO|Missouri", "MT|Montana", "NE|Nebraska", "NV|Nevada", "NH|New Hampshire", "NJ|New Jersey", "NM|New Mexico", "NY|New York", "NC|North Carolina", "ND|North Dakota", "OH|Ohio", "OK|Oklahoma", "OR|Oregon", "PA|Pennsylvania", "RI|Rhode Island", "SC|South Carolina", "SD|South Dakota", "TN|Tennessee", "TX|Texas", "UT|Utah", "VT|Vermont", "VA|Virginia", "WA|Washington", "WV|West Virginia", "WI|Wisconsin", "WY|Wyoming");

  ?>
  <select name=<?=$name;?> id="state" ><?
    foreach ($state_list as $s) {
        $values = explode("|",$s);
        ?><option value="<?=$values[0];?>" <?
                if($selected == $values[0]) { ?>SELECTED<? }
                ?>>
                <? if($full_state) { ?><?=$values[1];?><? } else { ?><?=$values[0];?><? } ?></option><?
    }
  ?></select><?
}
?>


<span class="InputDiscription">State: </span><div class="InputInner"><?=state_select('state',false,'AL'); ?></div><!----- END .InputInner ---------->
<?php
 $setError=$_GET['seterror']; 
if($setError == 1){

これはどう？他のphpファイルには $selectvalue=$_POST['hiddenfield'] を使用します

    var list = document.getElementById('state');
    var INDEX = list.selectedIndex;

    //Submit the form
    document.forms["theform"].submit();
}
</script>
</head>
<body>

<form action="otherfile.php" method="post" name="theform">
<?php

  $state_list = array("AL|Alabama","AK|Alaska","AZ|Arizona", "AR|Arkansas", "CA|California", "CO|Colorado", "CT|Connecticut", "DE|Delaware", "DC|Washington D.C.", "FL|Florida", "GA|Georgia", "HI|Hawaii", "ID|Idaho", "IL|Illinois", "IN|Indiana", "IA|Iowa", "KS|Kansas", "KY|Kentucky", "LA|Louisiana", "ME|Maine", "MD|Maryland", "MA|Massachusetts", "MI|Michigan", "MN|Minnesota", "MS|Mississippi", "MO|Missouri", "MT|Montana", "NE|Nebraska", "NV|Nevada", "NH|New Hampshire", "NJ|New Jersey", "NM|New Mexico", "NY|New York", "NC|North Carolina", "ND|North Dakota", "OH|Ohio", "OK|Oklahoma", "OR|Oregon", "PA|Pennsylvania", "RI|Rhode Island", "SC|South Carolina", "SD|South Dakota", "TN|Tennessee", "TX|Texas", "UT|Utah", "VT|Vermont", "VA|Virginia", "WA|Washington", "WV|West Virginia", "WI|Wisconsin", "WY|Wyoming");

otherfile.php でこれを入力すると、値を取得できます

<?php
echo "hiddenfield=".$_POST['hiddenfield'];
?>
