PHP $ _POST复选框 [英] PHP $_POST checkboxes

问题描述

我一直在添加现有代码，我的任务是为从MySQL数据库中提取的每一行添加复选框。问题是$ _POST在我告诉它取回复选框时返回null。



这是复选框创建循环：

Hi,
I've been adding to an existing code which I have the task of adding checkboxes to each row fetched from MySQL database. The problem is that $_POST is returning a null when I tell it to fetch checked boxes.

Here's the checkbox creation loop:

<pre lang="PHP">
      $RowCt = 0; //Row Counter
                while($Row = mysql_fetch_assoc($Result))
                {
                   
                    $k = $RowCt-1;
                    $Table.= "<td><input id=\"chkbx".$RowCt."\" onclick=\"bindCheckbox(".$RowCt.", ".$idValues[$k].")\" type=\"checkbox\" name='chkbx[]' value=".$k.">";

                    //Loop thru each field
                    foreach($Row as $field => $value)
                    {

                        $Table.= "<td nowrap=\"nowrap\">$value</td>";

                    }
                    $Table.= "</tr>";
                }

以及我想获得检查值的代码：

and the code where I want to get the checked values:

$doctorIds = $_POST['chkbx'];
		//echo $doctorname;
		//$q=select("SELECT * FROM `doctor` WHERE name = '$doctorname'");
		//$doctorname=$q[0]['id'];
		//echo $doctorname;	
		if (isset($doctorIds)||is_array($doctorIds)) {	
		foreach ($doctorIds as $key => $i){
		$b=execute_sql("INSERT INTO `doctorseller`(`doctorid`, `sellerid`) VALUES ('$i','$sellerid')");
		}

我有另一个表单元素，我使用相同的$ _POST方法但这给了我空的。我将不胜感激任何建议

I have another form element which i get using the same $_POST method but this is giving me nulls. I would appreciate any suggestions

推荐答案

当我告诉它取回复选框时，_POST返回null。



这是复选框创建循环：

_POST is returning a null when I tell it to fetch checked boxes.

Here's the checkbox creation loop:

<pre lang="PHP">

RowCt = 0; //行计数器
while（

RowCt = 0; //Row Counter while(

Row = mysql_fetch_assoc（

Row = mysql_fetch_assoc(
