Здравствуйте, я использую flexigrid и у меня есть проблема, я не знаю, почему она продолжает говорить
Invalid argument supplied for foreach()
и Undefined variable: rows
Я посмотрел на код, который мне кажется правильным, я не знаю, возможно, я упустил из виду, но вы можете мне помочь, спасибо
Вот мой код.
<?php
$page = isset($_POST['page']) ? $_POST['page'] : 1;
$rp = isset($_POST['rp']) ? $_POST['rp'] : 10;
$sortname = isset($_POST['sortname']) ? $_POST['sortname'] : 'name';
$sortorder = isset($_POST['sortorder']) ? $_POST['sortorder'] : 'desc';
$query = isset($_POST['query']) ? $_POST['query'] : false;
$qtype = isset($_POST['qtype']) ? $_POST['qtype'] : false;
$usingSQL = true;
function runSQL($rsql) {
$db['default']['hostname'] = "localhost";
$db['default']['username'] = 'root';
$db['default']['password'] = "";
$db['default']['database'] = "testdb";
$db['live']['hostname'] = 'localhost';
$db['live']['username'] = 'root';
$db['live']['password'] = '';
$db['live']['database'] = 'testdb';
$active_group = 'default';
$base_url = "http://".$_SERVER['HTTP_HOST'];
$base_url .= str_replace(basename($_SERVER['SCRIPT_NAME']),"",$_SERVER['SCRIPT_NAME']);
$connect = mysql_connect($db[$active_group]['hostname'],$db[$active_group]['username'],$db[$active_group]['password']) or die ("Error: could not connect to database");
$db = mysql_select_db($db[$active_group]['database']);
$result = mysql_query($rsql) or die ($rsql);
return $result;
mysql_close($connect);
}
function countRec($fname,$tname) {
$sql = "SELECT count($fname) FROM $tname ";
$result = runSQL($sql);
while ($row = mysql_fetch_array($result)) {
return $row[0];
}
}
$sort = "ORDER BY $sortname $sortorder";
$start = (($page-1) * $rp);
$limit = "LIMIT $start, $rp";
$where = "";
if ($query) $where = " WHERE $qtype LIKE '%".mysql_real_escape_string($query)."%' ";
$sql = "SELECT * FROM city $where $sort $limit";
$result = runSQL($sql);
$total = countRec("ID","city $where");
if(!isset($usingSQL)){
include dirname(__FILE__).'/countryArray.inc.php';
if($qtype && $query){
$query = strtolower(trim($query));
foreach($rows AS $key => $row){
if(strpos(strtolower($row[$qtype]),$query) === false){
unset($rows[$key]);
}
}
}
//Make PHP handle the sorting
$sortArray = array();
foreach($rows AS $key => $row){
$sortArray[$key] = $row[$sortname];
}
$sortMethod = SORT_ASC;
if($sortorder == 'desc'){
$sortMethod = SORT_DESC;
}
array_multisort($sortArray, $sortMethod, $rows);
$total = count($rows);
$rows = array_slice($rows,($page-1)*$rp,$rp);
}
header("Content-type: application/json");
$jsonData = array('page'=>$page,'total'=>$total,'rows'=>array());
foreach($rows AS $row){ **//THIS IS MY LINE 82**
//If cell's elements have named keys, they must match column names
//Only cell's with named keys and matching columns are order independent.
$entry = array('id'=>$row['iso'],
'cell'=>array(
'ID'=>$row['ID'],
'Name'=>$row['Name'],
'CountryCode'=>$row['CountryCode'],
'District'=>$row['District'],
'Population'=>$row['Population']
),
);
$jsonData['rows'][] = $entry;
}
echo json_encode($jsonData);
Заранее спасибо.
