输入类型“数字”删除我的文本字段的值

Question

I wanted my text field to accept only numbers so I try to use HTML5 attribute using "number". But it removes the value inside my text field. here is my code

 <div class="form-wrapper-full-width form-wrapper">
   <div class="form-label">
        Company Business Number:
   </div>         
   <div class="form-info">
       <input type="number" name="business_number" title="Business Number" value="<?=$phone_num['business_number']?>">
   </div> 
 </div>

</div>

Answer 1

Are you sure that a value is set to $phone_num['business_number']? And are you sure that $phone_num['business_number'] contains only numbers?

If it is set just try removing short tags of PHP.

<div class="form-wrapper-full-width form-wrapper">
   <div class="form-label">
        Company Business Number:
   </div>           
   <div class="form-info">
       <input type="number" name="business_number" title="Business Number" value="<?php echo $phone_num['business_number']; ?>">
   </div>   
 </div>
