$id = $_GET['id'];
require('adminpanel/includes/application_top.php');
$sql = "SELECT * FROM drug_reviewpage WHERE fld_product_id='" . $id . "'";
$r = mysql_query($sql);
$res = mysql_fetch_array($r);
$result = array();
array_push($result, array(
"fld_review_message" => $res['fld_review_message'],
"fld_fullname" => $res['fld_fullname'],
"fld_rate" => $res['fld_rate'],
"fld_date" => $res['fld_date']
));
echo json_encode(array("result"=>$result));
mysql_close($conection);

When I am trying to decode JSON with this code the output is
ArrayArray ( [0] => )
I do not know why WordPress doesn't support this
<?php
global $wpdb;
$mylink = $wpdb->get_results( "SELECT option_value FROM wp_options WHERE option_id=62167", ARRAY_N );
$raw = stripslashes_deep($mylink);
$data = array();
foreach ($raw as $json) {
echo $json;
$item = #json_decode($json, true);
$data[] = $item;
print_r($data);
}
?>
Hello you need to unserealize the data first when your query get data from database,
That is serealized data and when we get it from db we need to unserealize it.
global $wpdb;
$mylink = $wpdb->get_results("SELECT option_value FROM wp_options WHERE option_id=1223",ARRAY_A);
$raw = stripslashes_deep($mylink);
$data = $raw[0]['option_value'];
$datas = unserialize($data);
foreach ($datas as $key => $value) {
print_r($value);
}
in app\tmp\cache\models there is a file called:
myapp_cake_model_default_mydb_users
The contents are:

Can I convert this (serialized php?) to SQL and recreate my table, if so how? Many thanks in advance.
In PHP create a file:
<?php
class AppSchema extends CakeSchema {
public function before($event = array()) {
return true;
}
public function after($event = array()) {
}
$dir = 'files/';
$files = [
'table_names' => 'myapp_cake_model_default_mydb_tablenames',
];
foreach ($files as $table => $file){
$content = file(realpath( $dir.$file ));
$content = unserialize($content[1]);
$info = null;
foreach ($content as $field => $prop){
$info .= "'$field' => array(";
foreach ($prop as $key => $value){
$info .= "'$key' => ";
if($key == 'null'){
$info .= empty($value)?'false':'true';
}elseif($key == 'default'){
$info .= empty($value)?'null':"'$value'";
}elseif($key == 'unsigned'){
$info .= empty($value)?'false':'true';
}else{
$info .= empty($value)?"''":"'$value'";
}
$info .= ", ";
}
$info .= "),\n";
}
echo "public $".$table." = array(
".$info."'indexes' => array(
'PRIMARY' => array('column' => 'id', 'unique' => 1),
),
'tableParameters' => array('charset' => 'utf8', 'collate' => 'utf8_general_ci', 'engine' => 'InnoDB')
);\n\n";
}
?>
}
Then run it in the browser and you should get some code to paste a the schema.php file. Then use the Cake console to create the tables in the MySQL database.
How can I return all results of yii\db\Query as an object from a query like this one?
$query = new Query;
$query->select('id, name')
->from('user')
->limit(10);
$rows = $query->all();
Try this way
use yii\db\Query;
$query = new Query;
// compose the query
$query->select('id, name')
->from('user')
->limit(10);
// build and execute the query
$rows = $query->all();
// accessing the value
foreach ($rows as $row){
echo $row['name'];
}
for accessing via $row->name;
try with
use common\models\User; // or you app or backend depend where you have models
$rows = User::find()->limit(10)->all();
foreach ($rows as $row){
echo $row->nome;
}
I have the following code :
<?php
try {
# MySQL with PDO_MYSQL
$DBH = new PDO("mysql:host=*****;dbname=****", "****", "*****");
$DBH->setAttribute( PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION );
# statement handle (prevents injection)
$STH = $DBH->prepare("SELECT Adresse FROM Agences");
$STH->execute();
# statement handle (prevents injection)
$STHNAMES = $DBH->prepare("SELECT `numero-agence` FROM Agences");
$STHNAMES->execute();
$storeArray = Array();
$nameArray = Array();
while ($row = $STH->fetch()) {
$storeArray[] = $row['Adresse'];
}
while ($row = $STHNAMES->fetch()) {
$nameArray[] = $row['numero-agence'];
}
echo json_encode(
Array("theAddress" => $storeArray,
"theName" => $nameArray)
);
}
catch(PDOException $e) {
echo 'There was an issue inserting thing into database: '.$e->getMessage();
}
?>
My question is : is there a way to combine the two queries and still have an associative array to send back to the client JSON-encoded ? (I am querying this bit of PHP with an ajax call, and need the resulting data)
Thanks.
Can be done in the same query:
# statement handle (prevents injection)
$STH = $DBH->prepare("SELECT Adresse, `numero-agence` FROM Agences");
$STH->execute();
$storeArray = Array();
$nameArray = Array();
while ($row = $STH->fetch()) {
$storeArray[] = $row['Adresse'];
$nameArray[] = $row['numero-agence'];
}
I am displaying an editable table in drupal with the following code
function _MYMODULE_sql_to_table($sql) {
$html = "";
// execute sql
$resource = db_query($sql);
// fetch database results in an array
$results = array();
while ($row = db_fetch_array($resource)) {
$results[] = $row;
$id = $row['id'];
$email = $row['email'];
$comment = $row['comment'];
// drupal_set_message('Email: '.$email. ' comment: '.$comment. ' id: '.$id);
}
// ensure results exist
if (!count($results)) {
$html .= "Sorry, no results could be found.";
return $html;
}
// create an array to contain all table rows
$rows = array();
// get a list of column headers
$columnNames = array_keys($results[0]);
// loop through results and create table rows
foreach ($results as $key => $data) {
// create row data
$row = array(
'edit' => l(t('Edit'),"admin/content/test/".$data['id']."/ContactUs", $options=array()),);
// loop through column names
foreach ($columnNames as $c) {
$row[] = array(
'data' => $data[$c],
'class' => strtolower(str_replace(' ', '-', $c)),
);
}
// add row to rows array
$rows[] = $row;
}
// loop through column names and create headers
$header = array();
foreach ($columnNames as $c) {
$header[] = array(
'data' => $c,
'class' => strtolower(str_replace(' ', '-', $c)),
);
}
// generate table html
$html .= theme('table', $header, $rows);
return $html;
}
// then you can call it in your code...
function _MYMODULE_some_page_callback() {
$html = "";
$sql = "select * from {contact3}";
$html .= _MYMODULE_sql_to_table($sql);
return $html;
}
However, I keep getting the mysql_num_rows() error as
Warning: mysql_num_rows(): supplied argument is not a valid MySQL result resource. What is causing it?
Which version of Drupal are you using?
try db_affected_rows()
or db_num_rows()
