基于用户选择的在while循环中获取变量？ [英] Get variable in while loop based on what user chooses?

问题描述

我想从deleteupload.php中删除一篇文章，因此我想访问product_id，这是提交后每行的唯一标识符。我已经将每个产品都包装在一个表单元素和一个提交按钮中。所以这个页面有多个表单元素。

这是我的代码：

 <$ c $ （$ row = mysql_fetch_array（$ loop））
 {
 $ proID = $ row ['product_id']; 
 
 echo'< table border ='0'width ='100％'align ='center'class ='centrebox'>< tr> 
< td width =' 25％'>。（$ row ['product_name']）。 < / td>。 
< td width = '35％'>。（$ row ['product_disc']）。< / td>; 
 
 echo'< td width =40％>< img width =100％height =300src =data：image / jpeg; base64，'。base64_encode $ row ['product_image']）。'/>< / td>< / tr> 
< td>< form method =postaction =deleteupload.php> 
< input type =submitname =$ proIDvalue =Delete>< / form>< / td>< / table>< br>'; 
 
 
 
 
 
 
 
这个while循环遍历sql表和回显列（product_name，product_disc和product_image）。
解决方案
 
 < table border ='0 'width ='100％'align ='center'class ='centrebox'> 
 <？php 
 while（$ row = mysql_fetch_array（$ loop））
 {
 $ proID = $ row ['product_id']; 
？> 
< tr> 
< td width = '25％'><？php（$ row ['product_name']）？>< / td> 
< td width = '35％'><？php（$ row ['product_disc']）？>< / td> 
< td width = '35％'> 
< a href =deleteupload.php？action = delete& id =<？php echo $ proID？>>< / a> 
< / td> 
 
<？php}？> 
< / table> 
 $ b $ ** deleteupload.php ** 
 
 <？php 
 if（$ _ GET ['action'] =='delete'）{
 
删除查询
} 
？> 
  
 
I want to delete a single post from deleteupload.php hence I want to access product_id which is the unique identifier of each row after submission. I have wrapped every product in a form element and a submit button. So the page has multiple form elements.

This is my code:
 while ($row = mysql_fetch_array($loop))
 {
  $proID = $row['product_id'];

 echo "<table border='0' width='100%' align='center' class='centrebox'><tr>
 <td width='25%'>".($row['product_name']) . "</td> " . "
 <td width='35%'>".($row['product_disc'])."</td>";

 echo '<td width="40%"><img width="100%" height="300"  src="data:image/jpeg;base64,'.base64_encode( $row['product_image'] ).'"/></td></tr>
 <td><form method="post" action="deleteupload.php">
 <input type="submit" name="$proID" value="Delete"></form></td></table><br>';

}
This while loop iterates through the sql table and echos the columns (product_name, product_disc, and product_image).
解决方案
<table border='0' width='100%' align='center' class='centrebox'>
<?php 
 while ($row = mysql_fetch_array($loop))
 { 
  $proID = $row['product_id'];
?>
 <tr>
 <td width='25%'><?php ($row['product_name'])?></td> 
 <td width='35%'><?php ($row['product_disc']) ?></td>
 <td width='35%'>
    <a href="deleteupload.php?action=delete&id=<?php echo $proID ?>"></a>   
 </td>

<?php } ?>
</table>

**deleteupload.php**

<?php
if($_GET['action']=='delete'){

    delete query
}
?>
