无法从html'form'获取值到'php'文件 [英] Unable to fetch value from html 'form' to 'php' file

问题描述

这是我的表格

this is my form

<form  method="POST" action="result.php">
<input type="text" value=" " name="q" size="10" id="searchfield" title="searchfield" onFocus="clearText(this)" onBlur="clearText(this)" />
<input type="submit" name="search" value="" alt="Search" id="searchbutton" title="Search" />

这是php文件

and this is the php file

<?php 
@session_start(); 
include 'connections.php';
if (isset($_POST['q']) && $_POST['q'] != "")
{// I am unable to enter here...
$q = $_POST['q'];
$min_length = 1;
if(strlen($q) >= $min_length)
{
....

我在提交价值后无法进入条件..谁能告诉我原因？

I am unable to enter in if condition after submitting the value.. can anyone tell me why?

推荐答案

_POST [ ' q']）&&

_POST['q']) &&

_POST [ ' q']！= < span class =code-string>）
{ // 我无法在这里输入...

_POST['q'] != "") {// I am unable to enter here...

q =

q =
