I'm getting errors decoding JSON string.
ERROR:
Uncaught SyntaxError: Unexpected token {
My php code:
<?php
$socket = $_GET["socket"];
$bd = new PDO("mysql:host=localhost;dbname=gestao_utilizadores" , "root" , "");
$getComponentes = $bd->prepare("SELECT * FROM componentes WHERE ( Socket=:socket )");
$getComponentes->bindValue(':socket' , $socket);
$getComponentes->execute();
$resultado = $getComponentes->fetchAll();
For ($i = 0; $i < $getComponentes->rowCount() ; $i++) {
$componentes = json_encode(array('tipo' => $resultado[$i]["Tipo"] , 'nome' => $resultado[$i]["Nome"] , 'socket' => $resultado[$i]["Socket"]));
echo $componentes;
}
?>
My Javascript code:
$.ajax({
url: 'compatibilidades.php',
data: {
socket: $("#board option:selected").attr('value')
},
success: function(dadosRecebidos) {
teste = JSON.parse(dadosRecebidos);
alert(teste);
}
});
The error is on javascript or PHP?
<?php
$socket = $_GET["socket"];
$bd = new PDO("mysql:host=localhost;dbname=gestao_utilizadores" , "root" , "");
$getComponentes = $bd->prepare("SELECT * FROM componentes WHERE ( Socket=:socket )");
$getComponentes->bindValue(':socket' , $socket);

array_push($arr, $componentes);
}
echo json_encode($arr);

Output the JSON only once, otherwise you end up with an output of several JSON strings, something like
{"key1": "value1", "key2": "value2"}{"key3": "value3"}
and that's not valid JSON

I'm just starting to learn Laravel and I'd like to create a rest api without a model because I don't use one because my data comes from an external api. I have already written a piece of code however I am facing an error during my javascript request. It tells me that my json is incorrect.
I think the error comes from my api mainly from the way I return my json. Could you help me?

coinChart.JS
let url = 'http://crypto-data/api/chart/bitcoin'
fetch(url)

console.log(response.json())
return response.json();
})
.then(function (response) {
console.log(response);
})
.catch(function (error) {
console.log('catch');
});
The connection with the api is correct (200) but at the level of the decoding of my json the execution goes directly in the catch:
Thank you in advance for your help
I have a function which allows me to save dropped objects for each process in loop. Fiddle here The problem i am creating an array for each process and store dropped items inside. Function i use to save droped items:
<script>
var LISTOBJ = {
saveList: function() {
$(".leader").each(function() {
var listCSV = [];
$(this).find("li").each(function(){
listCSV.push($(this).text());
});
var values = listCSV.join(', ');
$(".output").append("<input type='hidden' name='leader[]' value='"+values+"' />");
$("#output").append("<p>"+values+"</p>");
console.debug(listCSV);
});
}
}
</script>
And what i get after printing saved objects:
Array ( [0] => aaronjames,adelyn [1] => benny,bryanooi )
I want to store names in the database and im able to do it but it stores an array. So i am looking a way to break an array inside array, instead of storing a full array.
I have 2 tables: 'project' and 'process'. I am trying to insert names into 'process' table. I am able to do so. but it stays as an array.
Here is function i am using to store received value inside database. I am generating project number and using foreach to assign names for each process
function insertRecord(){
global $holdcode,$holdtitle,$projLeader,$projChecker,$holdremark,$holdprocess,$holdnumber,$procLeader,$procChecker, $prodStuff;
// To protect MySQL injection (more detail about MySQL injection)
$holdcode = cleanInputData($holdcode);
$holdtitle = cleanInputData($holdtitle);
$projLeader = cleanInputData($projLeader);
$projChecker = cleanInputData($projChecker);
$holdremark = cleanInputData($holdremark);
$holdcode = mysql_real_escape_string($holdcode);
$holdtitle = mysql_real_escape_string($holdtitle);
$projLeader = mysql_real_escape_string($projLeader);
$projChecker = mysql_real_escape_string($projChecker);
$holdremark = mysql_real_escape_string($holdremark);
$result = getLastProjectNo();
if (!$result) {
die('Invalid query: ' . mysql_error());
}
if(mysql_num_rows($result) == 0)
{
$year = date("y");
$month = date("m");
$number = sprintf("%04d", 1);
$yearStr = strval($year);
$monthStr = strval($month);
$numberStr = strval($number);
$projectNo = $yearStr . $monthStr . $numberStr;
}
else{
if ($row_last = mysql_fetch_array($result))
{
$row_last[0] = cleanOutputData($row_last[0]);
$projectNo = $row_last[0];
$extractedNumberStr = substr($projectNo, -4);
$extractedYearMonthStr = substr($projectNo, 0, 4);
$year = date("y");
$month = date("m");
$yearStr = strval($year);
$monthStr = strval($month);
$currentYearMonthStr = $yearStr . $monthStr;
if($extractedYearMonthStr == $currentYearMonthStr)
{
$extractedNumber = intval($extractedNumberStr);
$extractedNumber++;
$extractedNumber = sprintf("%04d", $extractedNumber);
$extractedNumberStr = strval($extractedNumber);
$projectNo = $currentYearMonthStr . $extractedNumberStr;
}
else
{
$number = sprintf("%04d", 1);
$projectNo = $currentYearMonthStr . $number;
}
}
}
mysql_set_charset('utf8');
//query result
$result = insertProject($projectNo,$_SESSION['login_user'],$holdcode,$holdtitle,$projLeader,$projChecker,$holdremark);
// Check result
if (!$result) {
die('Invalid query: ' . mysql_error());
}
$result = getLastProjectNo();
if (!$result) {
die('Invalid query: ' . mysql_error());
}
$result = getLastProjectNo();
if (!$result) {
die('Invalid query: ' . mysql_error());
}
if ($row_last = mysql_fetch_array($result))
{
$row_last[0] = cleanOutputData($row_last[0]);
$projectNo = $row_last[0];
if (is_array($holdprocess) || is_object($holdprocess))
{
foreach( $holdprocess as $code => $eq )
{
$record = insertProcess($projectNo,$eq,$holdnumber[$code],$procLeader[$code],$procChecker[$code], $prodStuff[$code]);
if (!$record) {
die('Invalid query: ' . mysql_error());
}
}
}
}
}
What I want is to break an array inside array.For example i have Array ( [0] => aaronjames,adelyn [1] => benny,bryanooi ) i need to break [0] => aaronjames,adelyn into something that will allow me to store each name for each row in the table
Let me show you a way to read array value:
for($x = 0; $x < count($array_name); $x++) {
echo $array_name[$x];
echo "<br>";
}
If you need to access an array of objects then, try this
foreach($array_name as $obj){
$status = $obj->status;
}
If you receive a combined string (like 'aaronjames,adelyn') from array, then you can split the combined string using 'explode()' function of Php
<?php
$str = "aaronjames,adelyn";
$str_array=(explode(",",$str));
for($i=0;$i<count($str_array);$i++)
echo $str_array[$i]."<br/>";
?>
I am doing something i don't understand how. written a php code in O.O.P and the value gotten from it are objects. but i want to convert this O.O.P object to JSON data to be used in by javascript. so I converted my converted my objects to array on the php end. the try to use the json_encode function on it the script just keep returning errors. so i tried using a function i scope out, it worked but the js keeps on rejecting the data.
Below is the JS file
var ajax = new XMLHttpRequest();
ajax.open('GET','user.php',true);
ajax.setRequestHeader("Content-type","application/json");
ajax.onreadystatechange = function(){
if(ajax.readyState == 4 && ajax.status ==200){
var data = JSON.parse(ajax.responseText.trim());
console.log(data);
console.log(data[username]);
}
}
ajax.send();
it will return this error "SyntaxError: JSON.parse: bad control character in string literal at line 1 column 129 of the JSON data"
without the JSON.parse it return undefind fro the data.username console log. Below is the PHP SCRIPT
//header("Content-type: application/json");
require_once 'core/init.php';
function array2json($arr) {
/*if (function_exists('json_encode')) {
echo "string";
return json_encode($arr);
}*/
$pars = array();
$is_list = false;
$keys = array_keys($arr);
$max_length = count($arr) - 1;
if (($keys[0] == 0) and($keys[$max_length] == $max_length)) {
$is_list = true;
for ($i = 0; $i < count($keys); $i++) {
if ($i != $keys[$i]) {
$is_list = false;
break;
}
}
}
foreach($arr as $key => $value) {
if (is_array($value)) {
if ($is_list) $parts[] = array2json($value);
else $part[] = '"'.$key.
':'.array2json($value);
} else {
$str = '';
if (!$is_list) $str = '"'.$key.

if (is_numeric($value)) $str. = $value;

$parts[] = $str;
}
}
$json = implode(',', $parts);

}
$user = new User();

PLEASE HELP ME OUT TO SORT THIS ERROR THANK YOU.
You need to set the response headers, and ensure you are not violating CORS:
/*
* Construct Data Structure
*/
$response =
[
'value1',
'value2'
];
/*
* Format Data
*/
$jsonResponse = json_encode ( $response, JSON_PRETTY_PRINT );
/*
* Prepare Response
*/
header('content-type: application/json; charset=UTF-8');
/*
* ONLY if you want/need any domain to be able to access it.
*/
header('Access-Control-Allow-Origin: *');
/*
* Send Response
*/
print_r ( $jsonResponse );
/*
* Return with intended destruction
*/
die;
Just use the json functions json_encode and json_decode to convert arrays into json string or vice versa:
$myArray = array("value1", "value2");
echo json_encode($myArray);
this is my php code,
$count=mysql_num_rows($query);
if ($count > 0) {
// output data of each row
$foodList[] = array();
while($row =mysqli_fetch_assoc($result))
{
$foodList[] = $row;
}
} else {}
echo json_encode($foodList);
this is my js code:
var $promise = $http.post('foodList.php');
$promise.then(function(msg){
var foodList = msg.data;
if (foodList)
{
//$scope.foodList = foodList;
alert(foodList);
}
else
{
//$scope.msg = "Error user name or password";
}
this is output:
$promise.then(function(msg){*msg = Object {data: Array[1], status: 200, config: Object, statusText: "OK"}*
var foodList = msg.data;*foodList = [Array[0]]*
So: actually 3 data in my data base, but in output just only Array[1]?
How to fix it ?
THX
Your count the $query variable so in your while loop use $query variable
<?php
$count=mysql_num_rows($query);
if ($count > 0) {
// output data of each row
$foodList = array();
while($row =mysqli_fetch_assoc($query))
{
$foodList[] = $row;
}
}
echo json_encode($foodList);
?>
Your php syntax and the usage of commands are wrong in some places. Here is the corrected code. Please compare and see the difference.
$count=mysql_num_rows($result);
if ($count > 0) {
// output data of each row
$foodList = array();
while($row =mysqli_fetch_assoc($result))
{
array_push($foodList, $row);
}
}
echo json_encode($foodList);
This should work if you are selecting the rows correctly.

Comment out the line:
echo 'length of the tables name: '.$resultsListTables.' ';
Also, when outputting JSON for an AJAX call, it's important to set the Content-type header using:
header('Content-type: application/json; charset=utf-8',true);
This php code doesn't seem to have syntax error. the problem probably lies on the included php's: "connect.php" and "JSON.php". could you please post them too so we can find the error.
Link this into the beginning of your PHP-file:
header("Content-Type: text/javascript; charset=utf-8");
