我有一个页面是根据用户在前一页上提交的信息动态创建的。例如,在第 1 页上,用户输入了一些部门名称。他们想输入多少就输入多少。在第 2 页,为在第一页输入的每个部门创建了多个部分。在这些部分中的每一个都将是表单,我目前已将其设置为使用变量 $a 创建表单的名称。单击每个部分中的提交按钮后,我需要知道如何发布这些项目。我尝试了几种不同的方法,但没有任何效果。我希望它只发布与提交按钮的 $a 具有相同 $a 值的项目。
$departmentSql = "SELECT * FROM b_departments WHERE loc_id='$locid' AND b_id = '$bid'";
$departmentResults = mysql_query($departmentSql,$con);
$a = 0;
while ($departmentRow = mysql_fetch_array($departmentResults)) {
$department = $departmentRow['b_dep_name'];
$departmentID = $departmentRow['dep_id'];
$b_departmentID = $departmentRow['b_dep_id'];
$a++;
echo "
<div id=depDiv>
<div id=depDivHeader>
".$department."
</div>
";
$areaSql = "SELECT * from areas WHERE dep_id = $departmentID ORDER BY area_name ASC";
$areaSqlResult = mysql_query($areaSql);
?>
<br />
<input type="hidden" name="bdep<?php echo $a;?>" value="<?php echo $b_departmentID; ?>" />
Add Area:
<select name="dep_area<?php echo $a;?>" type="menu">
<option value=""></option>
<?php while($areaRows=mysql_fetch_assoc($areaSqlResult)){?>
<option value="<?php echo "".$areaRows['area_id'].",".$areaRows['area_name']."" ?>"><? php echo $areaRows[ 'area_name'] ?></option>
<?php }
?>
</select>
<input type="submit" name="areaSub<?php echo $a;?>" value="Add" />
<?php
echo "</div>";
}
?>
*编辑我需要所有内容都采用一种形式,因为页面的重点是将稍后插入每个单独部分的所有值相加。*

我使用@dirt 的 jquery 建议解决了这个问题。
HTML:
$departmentSql = "SELECT * FROM b_departments WHERE loc_id='$locid' AND b_id = '$bid'";
$departmentResults = mysql_query($departmentSql,$con);
$a = 0;
while ($departmentRow = mysql_fetch_array($departmentResults)) {
$department = $departmentRow['b_dep_name'];
$departmentID = $departmentRow['dep_id'];
$b_departmentID = $departmentRow['b_dep_id'];
$a++;
echo "
<div id=depDiv>
<div id=depDivHeader>
".$department."
</div>
<div id=$a>
";
$areaSql = "SELECT * from areas WHERE dep_id = $departmentID ORDER BY area_name ASC";
$areaSqlResult = mysql_query($areaSql);
?>
<br />
<input type="hidden" name="bdep<?php echo $a ?>" value="<?php echo $b_departmentID; ?>" />
Add Area:
<select name="dep_area<?php echo $a ?>" type="menu">
<option value=""></option>
<?php while($areaRows=mysql_fetch_assoc($areaSqlResult)){?>
<option value="<?php echo "".$areaRows['area_id'].",".$areaRows['area_name']."" ?>"><? php echo $areaRows[ 'area_name'] ?></option>
<?php }
?>
</select>
<button type="submit" name="areaSub" value="<?php echo $a ?>" />Add</button>
<?php
echo "</div></div>";
} ?>
jQuery:
<script>
$(document).ready(function() {
$('#<?php echo $a ?>').submit(function() {
.post("include/action.php")
});
});
</script>
PHP:
if(isset($_POST['areaSub'])) {
$areaval = intval($_POST['areaSub']);
$area = mysql_real_escape_string($_POST["dep_area".$areaval.""]);
list($area_id, $area_name) = explode(',', $area, 2);
$bdep = mysql_real_escape_string($_POST["bdep".$areaval.""]);
echo $areaval;
echo $area_name;
echo $bdep;
}
