GETメソッドを持つ2つのフォームがあります。最初のフォームを送信すると、このURLが表示されます

http://127.0.0.1/astronomy/student_enrollment.php?class_name_data=1&classNameGetDetails=

GETメソッドもある2番目のフォームを送信すると。私のURLはこれに変更されました

http://127.0.0.1/astronomy/student_enrollment.php?class_name_for_enrollment=Planet&sy_for_enrollment=2012-2013&sy_for_enrollment=45&number_of_student_enrolled=&time_schedule_student=Monday+to+Friday+8%3A00-9%3A00&generateFields=Generate

最初のクエリ文字列が削除され、2番目のクエリ文字列に置き換えられました

URLを次のようにします

http://127.0.0.1/astronomy/student_enrollment.php?class_name_data=1&classNameGetDetails=&class_name_for_enrollment=Planet&sy_for_enrollment=2012-2013&sy_for_enrollment=45&number_of_student_enrolled=&time_schedule_student=Monday+to+Friday+8%3A00-9%3A00&generateFields=Generate

&2つのクエリ文字列は、ではなくの区切り文字と結合されます?。どうすればいいですか？

これは私のコードです

<div class="enrollmentContent">
    <div class="classNameChoices">
    <label>Choose Class Name</label>
    <form action="" method="get">

        <select name="class_name_data">

            );
            $class_name_query = show_filtered_rows($table, $data);
            while($rows = mysql_fetch_array($class_name_query)){
                $id = $rows['id'];
                $class_name = $rows['class_name'];
            ?>
            <option value="<?php echo $id; ?>"><?php echo $class_name; ?></option>

    </div>
    <?php

</div>

と私の機能

function show_filtered_rows($table, $data){
    foreach($data as $fields=>$field_data){
        $show_data[] = "`".$fields."` = '".$field_data."'";
    }
    return mysql_query("SELECT * FROM `$table` WHERE ".implode(" AND ",$show_data));
}

非表示の入力に値を設定する必要があります。

<input type="hidden" name="class_name_data" value="<?php echo $_GET['class_name_data']" />

そしてあなたの2番目のフォームを置きます。

最初のフォームの値を非表示の値として2番目のフォームに追加するだけです。

<input type="hidden" name="class_name_data" value="<?php echo $_GET['class_name_data']; ?>" />
<input type="hidden" name="classNameGetDetails" value="<?php echo $_GET['classNameGetDetails']; ?>" />

上記の2行が追加された完全なコードを次に示します。PHP関数は変更されません。

<div class="enrollmentContent">
    <div class="classNameChoices">

    <form action="" method="get">

            'teacher_id' => $session_id
            );
            $class_name_query = show_filtered_rows($table, $data);
            while($rows = mysql_fetch_array($class_name_query)){
