Question

我是使用mysql占位符的新手。我正在尝试，但进展并不顺利。据我所知，将绑定参数直接复制到书本之外时，我的绑定参数出现错误。

我犯了什么荒谬的明显错误？

echo <<<_END
<table>
<tr><td>Title </td><td>     <input type = "text" name = "title" size    =70></td></tr>
 <tr><td>Subtitle  </td><td> <input type = "text" name = "subtitle" size ="65"></td></tr>
 <tr><td>Description </td><td> <input type = "text" name = "description" size = "100"></td></tr>
<tr><td>location  </td><td>  <input type = "text" name = "location" size = "5"></td></tr>
<tr><td>pages   </td><td>   <input type = "number" name = "pages">.      </td></tr>
 <tr><td>Present   </td><td>  <input type= "number"   name = "present" min="2" max ="8"> </td></tr>    
</table>
<br>binding <br>Paperback<input type = "radio" name = "binding" value = "2" checked>
 Cloth<input type="radio" name="binding" value = "1"><br>
Index       <input type = "checkbox" name = "w_index">
 Maps   <input type = "checkbox" name= "w_maps">
Illustration <input type = "checkbox" name = "w_illustration">
Bibliography <input type = "checkbox"  name= "w_bibliograpghy">
 <br><br><br>
 <input type ='submit'  value = 'new book'>
 _END. ;

     if ( !( $ST=   $zx1->prepare("insert into books values (?,?,?,?,?,?,?,?,?,?) ")))
{echo'stage1';}
  $ST->bind_param('ssssiiiiii',$title,$subtitle,$description,$location,$page.   s,$present,$binding,$maps,$illustration,$index))
  {echo 'stage 2'};
 echo 'Binding parameters failed:  ('.$stmt->errno.')'.$stmt->error ;};
  if (! $ST->execute())
 {echo 'stage 3' ;};
?>

谢谢您的协助。我完全在海上
