for循环中的多个记录中的表单验证

Question

我在这里有一个php记录，我有一个多记录的编辑页面，并具有表单验证。我的问题是在我的循环调用多个记录。

就像在上面的图片，我的PR＃文本框有一个消息，甚至有000174名和000176有一个正确的输入两个PR＃。如何使我的验证仅适用于每个ID具有无效输入的文本框。

请帮忙吗？

<form name="register_form" id="register_form" action="" method="post"> 

<?php 
$id=$_POST['checkbox']; 
$drop=$_POST['drop']; 
$tier_two=$_POST['tier_two']; 
$N = count($id); 
for($i=0; $i < $N; $i++) 
{ 
    $result1 = $mysqli->query(" 
SELECT a.item_name, a.item_description, a.counter, b.counter, b.pr, b.total_quantity 
FROM app a 
LEFT OUTER JOIN purchase_request b 
ON a.counter=b.counter 
WHERE a.counter='$id[$i]' 
    "); 
    while ($row = $result1->fetch_assoc()) 
     { ?> 
<p> <label for="">ID</label> <input name="counter[]" type="text" value="<?php echo $row['counter'] ?>" readonly="readonly"/><span class="val_counter"></span> </p>    

    <p> <label for="">Item</label> <input name="item[]" type="text" value="<?php echo $row['item_name'] ?>" readonly="readonly"/><span class="val_item"></span> </p>    

    <p> <label for="">Description</label> <input name="desc[]" type="text" value="<?php echo $row['item_description'] ?>" readonly="readonly"/><span class="val_desc"></span> </p>    

    <p> <label for="">PR Quantity</label> 
      <input name="pr_qty[]" id="pr_qty[]" class="textbox tb1" type="text" value="<?php echo $row['total_quantity']; ?>" /> 
      <span class="val_pr_qty"></span> 
    </p>   

    <p> <label for="">PR #</label> <input name="pr[]" type="text" value="<?php echo $row['pr'] ?>" /><span class="val_pr"></span> </p>    
<br/> 
     <?php 
     } 
} 

?> 

<input name="submit" type="submit" id="sbtBtn" value="Update"> 
</form> 

这是我脚本

<script> 
jQuery(function($) { 
    var validation_holder; 

    $("form#register_form input[name='submit']").click(function() { 

    var validation_holder = 0; 

     var item    = $("form#register_form input[name='item']").val(); 
     var item_regex   = /^[a-zA-Z0-9]+$/; // reg ex cost check  
     var desc    = $("form#register_form input[name='desc']").val(); 
     var desc_regex   = /^[a-zA-Z0-9]+$/; // reg ex cost check  
     var pr_qty    = $("form#register_form input[name='pr_qty']").val(); 
     var pr_qty_regex  = /^[a-zA-Z0-9]+$/; // reg ex cost check 
     var pr     = $("form#register_form input[name='pr']").val(); 
     var pr_regex   = /^[0-9]+$/; // reg ex qty check 
     var counter    = $("form#register_form input[name='counter']").val(); 
     var counter_regex  = /^[0-9]+$/; // reg ex qty check 

     /* validation start */ 

     if(item == "") { 
      $("span.val_item").html("This field is Required.").addClass('validate'); 
      validation_holder = 1; 
     } else { 
      if(!item_regex.test(item)){ // if invalid phone 
       $("span.val_item").html("Invalid Special Characters!").addClass('validate'); 
       validation_holder = 1; 

      } else { 
       $("span.val_item").html(""); 
      } 
     } 

     if(desc == "") { 
      $("span.val_desc").html(""); 
     } else { 
      if(!desc_regex.test(desc)){ // if invalid phone 
       $("span.val_desc").html("Invalid Special Characters!").addClass('validate'); 
       validation_holder = 1; 

      } else { 
       $("span.val_desc").html(""); 
      } 
     } 

     if(pr_qty == "") { 
      $("span.val_pr_qty").html("This field is Required.").addClass('validate'); 
      validation_holder = 1; 
     } else { 
      if(!pr_qty_regex.test(pr_qty)){ // if invalid phone 
       $("span.val_pr_qty").html("Invalid Special Characters!").addClass('validate'); 
       validation_holder = 1; 

      } else { 
       $("span.val_pr_qty").html(""); 
      } 
     } 

     if(pr == "") { 
      $("span.val_pr").html("This field is required.").addClass('validate'); 
      validation_holder = 1; 
     } else { 
      if(!pr_regex.test(pr)){ // if invalid phone 
       $("span.val_pr").html("Integer Only is Allowed!").addClass('validate'); 
       validation_holder = 1; 

      } else { 
       $("span.val_pr").html(""); 
      } 
     } 

     if(counter == "") { 
      $("span.val_counter").html(""); 
     } else { 
      if(!counter_regex.test(counter)){ // if invalid phone 
       $("span.val_counter").html("Please Refresh to avoid database error!").addClass('validate'); 
       validation_holder = 1; 

      } else { 
       $("span.val_counter").html(""); 
      } 
     } 

     if(validation_holder == 1) { // if have a field is blank, return false 
      $("p.validate_msg").slideDown("fast"); 
      return false; 
     } validation_holder = 0; // else return true 
     /* validation end */  
    }); // click end 
}); // jQuery End 
</script> 

Answer 1

跨度标签的ID是相同的每个记录，因此，如果误差是存在的任何记录，将在每一个span标签中反映出来对每条记录record.Use不同的ID是解...

Answer 2

你必须循环一样，

$("input:text[name=counter]").each(function(){ 
    alert($(this).val()); 
}); 

每个输入10
