在php ci中发布数组数据后字符串更改

Question

i wanna post an array data in php codeigniter. this is a part of my code in view

 <input type="hidden" name="category[<?php echo $i; ?>]"
  value="<?php echo $info['category']; ?>  ">
 <?php var_dump($info['category']);?>

the result of above var_dump shows the correct string. for example:

string(7) "parquet"

but when i post the data to controller string changes and var_dump() result is:

string(9) "parquet "

my question is what's happening when i post data and how can i fix this issue.

Answer 1

It's because you have two space characters in your value before you end the quote.

value="<?php echo $info['category']; ?>  ">
