对于elseif条件中的每个循环不起作用

在我的索引文件项目中，我有以下代码。

<?php
include "app/config.php";
$browser_t="web";

if ($page_name=='') {
    include $browser_t.'/index.php';
}
elseif ($page_name=='index.php') {
    include $browser_t.'/index.php';
}
elseif ($page_name=='about?aboutus=aboutus') {
    include $browser_t.'/about/index.php';
}
elseif ($page_name=='about?aboutus=aboutus&aboutus_id=1') {
    include $browser_t.'/about/index.php';
}
elseif ($page_name=='about?aboutus=aboutus&aboutus_id=2') {
    include $browser_t.'/about/index.php';
}
elseif ($page_name=='about?aboutus=aboutus&aboutus_id=3') {
    include $browser_t.'/about/index.php';
}
elseif ($page_name=='about?aboutus=aboutus&aboutus_id=4') {
    include $browser_t.'/about/index.php';
}
elseif ($page_name=='about?aboutus=aboutus&aboutus_id=5') {
    include $browser_t.'/about/index.php';
}
?>

我想让它充满活力。所以，我正在使用以下查询。

<?php
include "app/config.php";
$browser_t="web";

if ($page_name=='') {
    include $browser_t.'/index.php';
}
elseif ($page_name=='index.php') {
    include $browser_t.'/index.php';
}
elseif ($page_name=='about?aboutus=aboutus') {
    include $browser_t.'/about/index.php';
}
elseif ($query="SELECT id FROM aboutus_tbl";
$result=mysql_query($query);
    foreach ($result as $value) {
        echo $page_name=='about?aboutus=aboutus&aboutus_id='.$value;
    }) {  
    include $browser_t.'/about/index.php';
}

它显示错误，我不知道怎么做？如何在这里使用foreach循环或while循环？请帮帮我。

<?php 

include "app/config.php";
$browser_t="web";

if ($page_name=='') {
    include $browser_t.'/index.php';
}
elseif ($page_name=='index.php') {

1）您需要在if条件之外写入查询。

2）$result=mysql_query($query)不用于从数据库中获取数据!!。

3）停止使用mysql，不推荐使用它。您可以使用mysqli或PDO

4）检查页面使用错误

ini_set('display_errors',1);
ini_set('display_startup_errors',1);
error_reporting(-1);

使用

更改代码 
<?php
include "app/config.php";
$browser_t="web";
$query="SELECT id FROM aboutus_tbl";
$result=mysql_query($query);
$row = mysql_fetch_assoc($result);

 $page_name1=='about?aboutus=aboutus&aboutus_id='.$row['id'];// assing to anothere variable

if ($page_name=='') {
    include $browser_t.'/index.php';
}
elseif ($page_name=='index.php') {
    include $browser_t.'/index.php';
}
elseif ($page_name=='about?aboutus=aboutus') {
    include $browser_t.'/about/index.php';
}
elseif ($page_name==$page_name1) {  
    include $browser_t.'/about/index.php';
}

答案 1 :(得分：0)

switch ($page){
  case ($page ==''):
  case ($page) == 'index.php':
    include $browser_t.'/index.php';

    break;
  // an other case 
  default:
    // add your query here
    $result =   mysql_query( "SELECT id FROM  aboutus_tbl;"
    if( mysql_num_rows($result)> 0 ){
      $result_data = mysql_fetch_row($result);
      foreach($result_data as $value) {
        echo $page_name ='about?aboutus=aboutus&aboutus_id='.$value;
     }  
     include $browser_t.'/about/index.php'; 
    break; 
   }
希望这有帮助。

你的问题在这里

elseif ($query="SELECT id FROM aboutus_tbl";
$result=mysql_query($query);
    foreach ($result as $value) {
        echo $page_name=='about?aboutus=aboutus&aboutus_id='.$value;
    }) {  
    include $browser_t.'/about/index.php';
}

我不确定您在该代码中尝试实现的目标，但您无法在elseif的括号之间进行SQL查询和foreach循环。您唯一可以拥有的是要评估为TRUE或FALSE的表达式。

<?php
include "app/config.php";
$browser_t="web";

$string = "";
$pg = "page_name";
$query =  "select id from task_assign";//your query goes here......
$result=mysql_query($query);
while($value = mysql_fetch_array($result)) 
{
        $string .= "else if($$pg == 'about?aboutus=aboutus&aboutus_id='.$value[id])
        {
            include $browser_t.'/about/index.php';
        }<br>";
}

if ($page_name=='') {
    include $browser_t.'/index.php';
}
elseif ($page_name=='index.php') {
   include $browser_t.'/index.php';
}
elseif ($page_name=='about?aboutus=aboutus') {
   include $browser_t.'/about/index.php';
}
echo $string
