Convert Ajax value to Another State - php

I have spent hours looking for help with returning to another text ini script from json encode. I have a Json_Encode output with value
[
{"JumStatus":3,"status_ppid":"1"},
{"JumStatus":4,"status_ppid":"2"},
{"JumStatus":1,"status_ppid":"3"},
{"JumStatus":1,"status_ppid":"6"}
]
url: "_DEFINE_GET/_GetData.php",
method: "GET",
success: function(data) {
console.log(data);
var sta = [];
var jum = [];
for(var i in data) {
sta.push(data[i].status_ppid);
jum.push(data[i].JumStatus);
}
var chartdata = {
labels: sta,
datasets: [{
backgroundColor: [
"#2ecc71",
"#f1c40f",
"#3498db",
"#ff5722",
"#34495e",
'#009688',
"#e91e63"
],
hoverBackgroundColor: [
'rgba(0,255,0,0.3)',
'rgba(255,255,0,0.3)',
'rgba(0,0,255,0.3)',
'rgba(255,0,0,0.3)',
'rgba(192,192,192,0.6)',
'rgba(42,176,99,0.63)',
'rgba(255,0,0,0.3)',
],
data: jum,
}]
};
And my label in labels: sta, is output [1,2,3,6]
But i want to convert that output to another state when in php we use
if ($status_ppid=="1" ) { $status_ppid=="Application"; }
elseif ($status_ppid=="2" ) { $status_ppid=="Proccess"; }
elseif ($status_ppid=="3" ) { $status_ppid=="Staff Validation"; }
elseif ($status_ppid=="4" ) { $status_ppid=="Analys Validation"; }
elseif ($status_ppid=="5" ) { $status_ppid=="Manager Validation"; }
elseif ($status_ppid=="6" ) { $status_ppid=="Done"; }
And my question how to convert like that in Javascript ajax like in PHP?
My Expected value is after change the value but i dont know how to change the value ini script
label is output ['Application','Proccess,Staff','Validation','Done']
Need Help master
I am beginner in php

I think you should create method for convert status like this
function convertStatus(id) {
var status = "";
if (id == '1') {
status = "Application";
} else if (id == '2') {
status = "Proccess";
} else if (id == '3'){
status = "Staff Validation";
} else if (id == '4'){
status = "Analys Validation";
} else if (id == '5'){
status = "Manager Validation";
} else if (id == '6'){
status = "Done";
}
return status;
}
And you call the method before push to array
sta.push(convertStatus(data[i].status_ppid));

How to check the condition in the jquery?

I am create the js tree to show the folder path name, and my problem is how to check the condition if database table status is 0(inactive) then will show the line-through in the js tree. Else table status is 1(active) just back to normal. Below is my coding:
<?php
$folderData = mysqli_query($mysql_con,"SELECT * FROM filing_code_management");
$folders_arr = array();
while($row = mysqli_fetch_assoc($folderData)){
$parentid = $row['parentid'];
if($parentid == '0') $parentid = "#";
$selected = false;$opened = false;
if($row['id'] == 2){
$selected = true;$opened = true;
}
$folders_arr[] = array(
"id" => $row['id'],
"parent" => $parentid,
"text" => $row['name'] . ' ' . "<span id='category'>". $row['category']."</span>",
"category" => $row['category'],
"status" => $row['status'], // status 0 is inactive, status 1 is active
"state" => array("selected" => $selected,"opened"=>$opened)
);
}
?>
<script style="text/javascript">
var StrikeNodes = function(nodelist) {
var tree = $('#folder_jstree').jstree(true);
nodelist.forEach(function(n) {
tree.get_node(n.id).a_attr.style = "text-decoration:" + getStrike(parseInt(n.text.substr(0, 3), 10));
tree.redraw_node(n.id); //Redraw tree
StrikeNodes(n.children); //Update leaf nodes
});
};
var getStrike = function(i) {
if (status = '0' ) {
return "line-through;";
} else {
return "";
}
};
$('#folder_jstree').bind('load_node.jstree', function(e, data) {
var tree = $('#folder_jstree').jstree(true);
StrikeNodes(tree.get_json());
});
</script>
Now my output show all the all the line-through in the js tree, not detect which is active or inactive.
My working JSFiddle code here: https://jsfiddle.net/ason5861_cs/9x0dsotz/3/
Hope someone can guide me which part I am getting wrong.
looking at your code. you are not comparing the status it should be status == '0' instead of status = '0'
also there is available option that jstree provided. data option this can be anything you want. it is metadata you want attached to the nod. you will be able to access and modify it any time later - it has no effect on the visuals of the node.
[{
"id": "1",
"parent": "#",
"text": "100 PENTADBIRAN <span id='category'>JTM<\/span>",
"category": "JTM",
"data": { "status": 0 },
"state": {
"selected": false,
"opened": false
}
}]
var StrikeNodes = function(nodelist) {
var tree = $('#folder_jstree').jstree(true);
nodelist.forEach(function(n) {
tree.get_node(n.id).a_attr.style = "text-decoration:" + getStrike(n.data.status);
tree.redraw_node(n.id); //Redraw tree
StrikeNodes(n.children); //Update leaf nodes
});
};
var getStrike = function(status) {
if (status == 0) {
return "line-through;";
}
return "";
};

JQUERY and AJAX Pagination and Calling Data

I am facing the following problem, I have a page of products with ajax pagination where users is able to select products in a form, the selected products save their id values in an array, but my problem is when the user goes to page 2 then he go back to page 1 he is able to choose the same product where I need to be the array ids unique, where user is able to select only the product 1 time even if he goes to page 2 or 3 and come back to previous pages
my ajax code:
$(".pageNumber").on("click",function(){
pageID = this.id;
var data_string = 'pageID='+pageID;
$.ajax({
type: "POST",
url: "loadData.php",
data: { "pageId" : pageID, "catid" : catid, "subid" : subid, "filter" : filter, "view" : view_type , "items" : itemArrayList},
cache: false,
success: function (result) {
$(".pageNumber").removeClass("number-page-active");
$("#"+pageID).addClass("number-page-active");
$("#results1").hide();
$("#results").html(result);
console.log(result);
if ($(".number-page-active").attr('id') == 1) {
$('#sub1').attr("style","display:none") ;
}
if ($(".number-page-active").attr('id') != 1) {
$('#sub1').attr("style","display:block") ;
}
if ($(".number-page-active").attr('id') == <?php echo $pageLast ?>) {
$('#add1').attr("style","display:none") ;
}
if ($(".number-page-active").attr('id') != <?php echo $pageLast ?>) {
$('#add1').attr("style","display:block") ;
}
}
});
The list of selected products are saved in array as follow:
$("#quotationSubmit").on("click",function(){
console.log(itemArrayList);
$("#itemListArray").val(itemArrayList);
});
var itemSelected = 0;
itemArrayList = [];
function image(divId) {
if (itemSelected < 0) {
itemSelected = 0;
}
var idDiv = 1;
for (idDiv; idDiv <= 100; idDiv++) {
var divDivId = "" + idDiv;
var divDivId0 = "" + idDiv;
if (divDivId === divId || divDivId0 === divId) {
break;
}
}
if ($("#quotation-form").css("display") === "block") {
if ($("#" + idDiv).hasClass("selected-div") === true || $("#" +
idDiv).hasClass("selected-div")) {
$("#" + idDiv).removeClass("selected-div");
$("#" + idDiv).removeClass("selected-div");
itemSelected--;
index = $.inArray(divId,itemArrayList);
itemArrayList.splice(index,1);
console.log(itemArrayList);
} else {
$("#" + idDiv).addClass("selected-div");
$("#" + idDiv).addClass("selected-div");
itemSelected++;
itemArrayList.push(divId);
console.log(itemArrayList);
}
if (itemSelected === 0) {
document.getElementById("quotationText").innerHTML = "Please Select an item";
} else {
if (itemSelected === 1) {
document.getElementById("quotationText").innerHTML = "You have 1 item Selected";
} else {
document.getElementById("quotationText").innerHTML = "You have " + itemSelected + " items Selected";
}
}
} else {
var imageMe = $("#" + divId).find('img').attr('src');
document.getElementById('image00').src = imageMe;
setTimeout(function () {
$(".modal-for-image").removeClass("left-modal-image");
}, 100);
}
}

Search bar with jquery dropdown showing results

When the user types something into the search bar I would like the results bellow to link to a page when you click it instead of filling the search bar with whatever you clicked. I'm very new to Jquery and I found this tutorial online but it isn't doing exactly what I wanted it to.
Index.php (Just showing some of the head and the body)
<script>
$(document).ready(function(){
$("#tag").autocomplete("autocomplete.php", {
selectFirst: true
});
});
</script>
</head>
<body>
<label>Tag:</label>
<input name="tag" type="text" id="tag" size="20" style="width:541px; height:23px; font-size:16px; text-indent:5px;" placeholder="Search foods, shopping lists, meal plans and recipes" />
</body>
autocomplete.php (Even with the and tags I was unable to achieve the linking to another page.)
<?php
$q=$_GET['q'];
$my_data=mysql_real_escape_string($q);
include ("connect.php");
$sql="SELECT id, name, description, foodgroup FROM foods WHERE name LIKE '%$my_data%' ORDER BY name";
$result = mysql_query($sql);
if($result) {
while($row=mysql_fetch_array($result)) {
print "<a href='food.php?foodGroup=" . $row['foodgroup'] . "&name=" . $row['name'] . "&desc=" . $row['description'] . "&foodID=" . $row['id'] . "'><div id='resultContainerDiv'><span id='resultText'>" . $row['name'] . " - " . $row['description'] . "</span></div></a>\n";
}
}
?>

Thank you,
Ryan
In the search script you have an error:
<?php
$q=$_GET['q'];
$my_data=mysql_real_escape_string($q);
include ("connect.php");
mysql_real_escape_string will return false (the equivalent of an empty string) if there is no database connection yet so you are effectively emptying your search string.
You need to switch that around:
<?php
$q=$_GET['q'];
include ("connect.php");
$my_data=mysql_real_escape_string($q);
You should also add error handling to your database calls and move to PDO or mysqli if possible as the mysql_* functions are deprecated.

help me to reduce the amount of code in a jquery script

Currently I'm using this jquery script combining with php (doesn't matter):
<script type="text/javascript" charset="utf-8">
$(document).ready(function(){
var select = "<?php if_exist($select, ''); ?>";
var event = "<?php if_exist($event, 'click'); ?>";
var display = "<?php if_exist($display, '#display'); ?>";
var loading = "<?php if_exist($loading, '#loading'); ?>";
var datatype = "<?php if_exist($datatype, 'json'); ?>";
var cache;
if (event == "submit"){ $("input:submit").hide(); }
$(select).bind( event , function(key){
if ( event == "keypress" ) {
if ( key.which == <?php if_exist($keycode, '13'); ?> ) {
$(loading).show();
$.post(
$(select).attr("action"),
$(select).serialize(),
function(data){
if (datatype == "html" || datatype == "text"){ var returned = data; }
if (datatype == "json"){ var returned = data<?php if_exist($return, '.return'); ?>; }
if (returned != cache)
{
cache = returned;
if (datatype == "html" || datatype == "text"){ $(display).hide().html(data).fadeIn(); }
if (datatype == "json"){ $(display).hide().autoRender(data).fadeIn(); }
$(loading).hide();
}
},
datatype
);
return false;
};
}
else
{
$.post(
$(select).attr("action"),
$(select).serialize(),
function(data){
if (datatype == "html" || datatype == "text"){ var returned = data; }
if (datatype == "json"){ var returned = data<?php if_exist($return, '.returnValue'); ?>; }
if (returned != cache)
{
cache = returned;
if (datatype == "html" || datatype == "text"){ $(display).hide().html(data).fadeIn(); }
if (datatype == "json"){ $(display).hide().autoRender(data).fadeIn(); }
$(loading).hide();
}
},
datatype
);
if ($event == 'submit') { return false;}
}
});
});
</script>
I want to reduce the amount of code used in this script, I think we can surely reduce the amount of code in this script by giving our attention to the line #11 which contains: if ( event == "keypress" ) {, because in the next else statement the same code is repeated twice, but how can we do this? Any idea?
The following piece looks duplicated:
$.post(
$(select).attr("action"),
$(select).serialize(),
function(data){
if (datatype == "html" || datatype == "text"){ var returned = data; }
if (datatype == "json"){ var returned = data; }
if (returned != cache)
{
cache = returned;
if (datatype == "html" || datatype == "text"){ $(display).hide().html(data).fadeIn(); }
if (datatype == "json"){ $(display).hide().autoRender(data).fadeIn(); }
$(loading).hide();
}
},
datatype
);
You should consider moving it's functionality to a function (sic)!
In addition to Vlad's answer: Remove the unnecessary if query and variable assignment:
$.post(
$(select).attr("action"),
$(select).serialize(),
function(data) {
// in every case, data is assigned to another variable which is
// unnecessary as well
// if (datatype == "html" || datatype == "text"){ var returned = data; }
// if (datatype == "json"){ var returned = data; }
if (data != cache) {
cache = data;
}
if (datatype == "html" || datatype == "text") {
$(display).hide().html(data).fadeIn();
}
else if (datatype == "json"){
$(display).hide().autoRender(data).fadeIn();
}
$(loading).hide();
}
}, datatype );
