问题描述
无论如何,现在按钮:
< button type =buttononclick =subForm()name =delid =deletebuttonvalue ='。org。'>删除<按钮>
以下是我目前的验证:
< script type =text / javascript>
函数subForm()
{
if(confirm(你确定要删除它?))
document.forms [addorg]。submit() ;
else
返回false;
}
< / script>
以下是我的脚本:
if(isset($ _ POST [del])&&($ _POST ['del']!=='')){
$ del = mysql_real_escape_string(html2txt($ _ POST ['del']));
$ resfile = mysql_query('从组织中选择file_loc WHERE org_id ='。$ del);
$ org_name = mysql_real_escape_string(html2txt($ _ POST ['orgname']));
if(!$ resfile)
header('Location:'。$ admin。'?error = query');
while($ filerow = mysql_fetch_array($ resfile)){
$ fileplace = $ filerow ['file_loc'];
unlink(。。$ fileplace);
rmdir($ org_name);
}
mysql_query(从组织中删除org_id ='。$ del。');
header('Location:'。$ admin);
}
它目前不删除我想要的记录。
解决方案
您可以使用< ; input type =hidden>
:
echo'< input type =hidden name =org_idvalue ='。$ org_id。'/>'
应显示如下内容:
< input type =hiddenname =org_idvalue =1/>
使用此代码,您可以使用以下方式访问隐藏的字段数据:
$ org_id = $ _POST ['org_id'];
So I am trying to submit a variable and the name of the variable via a form. I switched a button from submit to button because I need additional validation.
Anyway, here's the button now:
<button type="button" onclick="subForm()" name="del" id="deletebutton" value="'.$org.'">Delete</button>
Here's my current validation:
<script type="text/javascript">
function subForm()
{
if(confirm("Are you sure you want to delete this?"))
document.forms["addorg"].submit();
else
return false;
}
</script>
And here's my script on the other side:
if (isset($_POST["del"]) && ($_POST['del'] !== '')) {
$del = mysql_real_escape_string(html2txt($_POST['del']));
$resfile = mysql_query('SELECT file_loc from organization WHERE org_id = '.$del);
$org_name = mysql_real_escape_string(html2txt($_POST['orgname']));
if (!$resfile)
header('Location: '.$admin.'?error=query');
while ($filerow = mysql_fetch_array($resfile)) {
$fileplace = $filerow['file_loc'];
unlink(".".$fileplace);
rmdir($org_name);
}
mysql_query("DELETE from organization where org_id='".$del."'");
header('Location: '.$admin);
}
It is not currently deleting the records that I want. How do I pass along the "del" name to the other page?
解决方案
You can use <input type="hidden">
:
echo '<input type="hidden" name="org_id" value="'.$org_id.'" />'
This should render something like:
<input type="hidden" name="org_id" value="1" />
Using this code you can access the hidden field data using:
$org_id = $_POST['org_id'];
