原标题:php function wont work more than once

我发挥了职能,让我了解用户名称。 不同的用户先令将同时使用,这样功能将多次使用。 它对一名用户进行罚款,但如果有一个以上用户,则给我一个错误。 错误是“战争:我sql_select_db():提供的论点不是有效的MySQL-Link资源”。

法典

<?php 

function user_details($user_id) {

require_once( ../Connections/runner.php ); 

if (!function_exists("GetSQLValueString")) {
function GetSQLValueString($theValue, $theType, $theDefinedValue = "", $theNotDefinedValue = "") 
{
  $theValue = get_magic_quotes_gpc() ? stripslashes($theValue) : $theValue;

  $theValue = function_exists("mysql_real_escape_string") ? mysql_real_escape_string   ($theValue) : mysql_escape_string($theValue);

  switch ($theType) {
    case "text":
      $theValue = ($theValue != "") ? " " . $theValue . " " : "NULL";
      break;    
    case "long":
    case "int":
      $theValue = ($theValue != "") ? intval($theValue) : "NULL";
      break;
    case "double":
      $theValue = ($theValue != "") ? " " . doubleval($theValue) . " " : "NULL";
      break;
    case "date":
      $theValue = ($theValue != "") ? " " . $theValue . " " : "NULL";
      break;
    case "defined":
      $theValue = ($theValue != "") ? $theDefinedValue : $theNotDefinedValue;
      break;
  }
  return $theValue;
}
}

$colname_users = $user_id;
$first_name = "";
$last_name = "";
mysql_select_db($database_runner, $runner);
$query_users = sprintf("SELECT first_name, last_name, profile_img_small FROM sign_up WHERE   user_id = %s", GetSQLValueString($colname_users, "int"));
$users = mysql_query($query_users, $runner) or die(mysql_error());
$row_users = mysql_fetch_assoc($users);
$totalRows_users = mysql_num_rows($users);
$first_name = $row_users[ first_name ];
$last_name = $row_users[ last_name ];
$profile_sml = $row_users[ profile_img_small ];

echo "$first_name $last_name";
}



?>

<?php
$user_id = 10;
?>

<a href="*"><?php user_details("$user_id"); ?></a>

<?php
$user_id = 9;
?>

<a href="*"><?php user_details("$user_id"); ?></a>
最佳回答

每当你行使职能时,你都会再次试图要求提交文件。 既然你再说不要求这样做,那么它就会看到,它早就要求它来做“,从而忽视了它。 因此,这些变量在你第二次称呼时就不存在,而功能必然无所作为。 我完全感到惊讶的是,它没有产生其他错误,因为整个档案缺失。 这绝不能是极其重要的。
