[RESOLVED] JavaScript Array to PHP post
I have this java array:
Code:
j_cdb = Array({"cid":"43","pid":"2","name":"ATV","srch":"ATV"},{"cid":"44","pid":"8","name":"AU Jobs","srch":"AU Jobs"},{"cid":"20","pid":"1","name":"Accommodation","srch":"Accommodation"},{"cid":"21","pid":"1","name":"Accounting","srch":"Accounting"},{"cid":"22","pid":"8","name":"Accounting & Finance Jobs","srch":"Accounting & Finance Jobs"},{"cid":"23","pid":"1","name":"Advertising & Design","srch":"Advertising & Design"},{"cid":"24","pid":"1","name":"Advertising & Marketing","srch":"Advertising & Marketing"}, etc...)
document.getElementById("theA").value=j_cdb; //this isn't working
I want to post it and process it in PHP. I have a hidden field (theA) and the submit button. When this code executes:
PHP Code:
if (isset($_POST['theA'])) {
var_dump($_POST['theA']);
}
I get:
Code:
string(8719) "[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object], etc....
I have tried json.stringfy / json decode. I am very new at this (java / php) so any guidance would be appreciated.
Re: Java Array to PHP post
I thought a class might help me see what the problem is:
Code:
// category class
function catg (a) {
this.cid = a['cid'];
this.pid = a['pid'];
this.name = a['name'];
this.srch = a['srch'];
catg.prototype.opt = function () {
}
catg.prototype.toPHP = function () {
return '{"cid":"' + this.cid + '","pid":"' + this.pid + '","name":"' + this.name + '","srch":' + this.srch +'"},';
}
}
newcat = Array();
function allCats(but) {
for (i = 0; i < j_cdb.length; ++i) {
foo = new catg(j_cdb[i]);
newcat.push(foo);
}
test = "";
for (i = 0; i < newcat.length; ++i) {
foo = newcat[i];
test += foo.toPHP;
}
// test = test.substring(0,test.length-1);
document.getElementById("test").innerHTML=test;
// document.getElementById("theA").value= test;
}
Re: Java Array to PHP post
Try this way:
PHP Code:
<?php
if(isset($_POST['submit']))
{
$str = json_decode($_POST['str'], true);
var_dump($str);
}
?>
<html>
<head>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.8.2/jquery.min.js"></script>
<script>
var j_cdb = Array({"cid":"43","pid":"2","name":"ATV","srch":"ATV"},{"cid":"44","pid":"8","name":"AU Jobs","srch":"AU Jobs"},{"cid":"20","pid":"1","name":"Accommodation","srch":"Accommodation"},{"cid":"21","pid":"1","name":"Accounting","srch":"Accounting"},{"cid":"22","pid":"8","name":"Accounting & Finance Jobs","srch":"Accounting & Finance Jobs"},{"cid":"23","pid":"1","name":"Advertising & Design","srch":"Advertising & Design"},{"cid":"24","pid":"1","name":"Advertising & Marketing","srch":"Advertising & Marketing"});
$(document).ready(function(){
$('#prepare').click(function(){ // prepare button inserts the JSON string in the hidden element
$('#str').val(JSON.stringify(j_cdb));
});
});
</script>
</head>
<body>
<button id="prepare">Prepare</button>
<form method="post">
<input type="hidden" id="str" name="str" value="" />
<input type="submit" name="submit" value="Submit" />
</form>
</body>
</html>
Hope it helps :wave:
Re: Java Array to PHP post
This works. All of this is about manipulating a one to many relationship (adjacency model). Now that I can get the array into java, and back, I can work on moving things from one list to another.
PHP Code:
<?php
if (isset($_POST['theA'])) {
$temp = str_replace('\\', '', $_POST['theA']); // get rid of \
$temp = str_replace('][', '', $temp); // get rid of trailing ][
$theA = json_decode($temp, true); // create array
print_r($theA);
foreach ($theA as $value) {
echo $value['name'] . '</br>';
}
}
?>
<script type='text/javascript'>
<?php
$j_cdb = $jcats->toJson($jcats->catsdb);
// create java array
$j_cdb=str_replace('[','',$j_cdb);
$j_cdb=str_replace(']','',$j_cdb);
echo "j_cdb = Array(". $j_cdb . ");\n";
?>
newcat = Array();
function allCats(but) {
for (i = 0; i < j_cdb.length; ++i) {
foo = new catg(j_cdb[i]);
newcat.push(foo);
}
test = "";
for (i = 0; i < newcat.length; ++i) {
foo = newcat[i];
test += foo.toPHP;
}
$('#theA').val(JSON.stringify(j_cdb));
}
</script>
<div data-role="content">
<h1>jcmo Category Management</h1>
<div id="test">*</div>
<table border="1" cellpadding="2">

<td>Main</td>

Re: JavaScript Array to PHP post
So I thought that this(lvl0) would work:
Code:
j_cdb = Array({"cid":"43","pid":"2","name":"ATV","srch":"ATV"},{"cid":"44","pid":"8","name":"AU Jobs","srch":"AU Jobs"},{"cid":"20","pid":"1","name":"Accommodation","srch":"Accommodation"},{"cid":"21","pid":"1","name":"Accounting","srch":"Accounting"},{"cid":"22","pid":"8","name":"Accounting & Finance Jobs","srch":"Accounting & Finance Jobs"},{"cid":"23","pid":"1","name":"Advertising & Design","srch":"Advertising & Design"},{"cid":"24","pid":"1","name":"Advertising & Marketing","srch":"Advertising & Marketing"}, etc...)
liproto = '<li id="_CID_" onClick="">_NAME_</li>' + '\n';
function allCats() {
toJstring();
}
function toJstring(){
$('#theA').val(JSON.stringify(j_cdb));
}
function lvl0(){
// build main level categories
temp = '';
for (i = 0; i < j_cdb.length; ++i) {
if (j_cdb[i]['cid'] == 0){
foo = liproto.replace('_CID_', j_cdb[i]['cid']);
foo = liproto.replace('_NAME', j_cdb[i]['name']);
temp += foo;
}
}
document.getElementById("l0").innerHTML = temp;
}
$(document).ready(function() {
allCats();
lvl0();
});
The function lvl0 doesn't appear to see the elements inside of j_cdb.
Re: Java Array to PHP post
Code:
var j_cdb = Array({"cid":"43","pid":"2","name":"ATV","srch":"ATV"},{"cid":"44","pid":"8","name":"AU Jobs","srch":"AU Jobs"},{"cid":"20","pid":"1","name":"Accommodation","srch":"Accommodation"},{"cid":"21","pid":"1","name":"Accounting","srch":"Accounting"},{"cid":"22","pid":"8","name":"Accounting & Finance Jobs","srch":"Accounting & Finance Jobs"},{"cid":"23","pid":"1","name":"Advertising & Design","srch":"Advertising & Design"},{"cid":"24","pid":"1","name":"Advertising & Marketing","srch":"Advertising & Marketing"});
$(document).ready(function(){
lvl0(); //call the function
function lvl0(){
//console.log(j_cdb);
temp = '';
for (i = 0; i < j_cdb.length; ++i) {
if (j_cdb[i]['cid'] == '43'){
temp += j_cdb[i]['name'] + ',';
}
}
$('#txt').html(temp); //display it
}
});
I just tried it like above and it worked. Each field is a string. So, the cid might also be a string value.
:wave:
Re: Java Array to PHP post
I haven't tried this yet, but the clarity of the morning makes me want to ask myself why am I so blind. The cid should never be 0! That is a big DUH! to me. Thanks for pointing the obvious!!!! Thanks for your patience.
I would up vote you again if I could.
Re: JavaScript Array to PHP post
:) So here is a near finished version. This allows me to work on the categories without server intervention.
PHP Code:
liproto = '<li class="catmgmtli" id="_CID_" onClick="filllvl(this.id)" onDblClick="mvthisdbl(this.id)" >_NAME_</li>' + '\n';
function toJstring() {
$('#theA').val(JSON.stringify(j_cdb));
}
var lstcid = '0'; //last cid selected
var mv2cid = '0'; //move to cid
var mv2ok = true;
var mvtcid = Array(); // move this cid
function mvthisdbl(cidlvl) {
filllvl(cidlvl);
mvthis();
}
function setmv2() {
if (mv2ok) {
document.getElementById("mv2").innerHTML = document.getElementById("lastitem").innerHTML;
mv2cid = lstcid;
document.getElementById("lastitem").innerHTML = '';
}
}
function mvthis() {
if (mv2cid != lstcid) {
mvtcid.push(lstcid);
document.getElementById("mvt").innerHTML += "•" + document.getElementById("lastitem").innerHTML + "\n";
document.getElementById("lastitem").innerHTML = '';
}
}
function moveit(clr) {
if (clr == 1) {
//do move
while (mvtcid.length > 0) {
foo = mvtcid.pop()
for (i = 0; i < j_cdb.length; ++i) {
if (j_cdb[i]['cid'] == foo) { // look for move this
j_cdb[i]['pid'] = mv2cid;
break;
}
}
}
}
toJstring();
//refresh
filllvl('0.0'); //set main level items
lstcid = '0'; //last cid selected
mv2cid = '0'; //move to cid
mv2ok = true;
mvtcid = Array(); // move this cid
document.getElementById("lastitem").innerHTML = '';
document.getElementById("mv2").innerHTML = ''
document.getElementById("mvt").innerHTML = '';
}
function filllvl(cidlvl) {
// build main level categories
// lvl = 'pid.level'
var cl = cidlvl.split('.');
var pid = cl[0];
cl[1] = parseInt(cl[1]);
var lvl = cl[1] + 1; //next level
temp = '';
if (cl[1] <= 4) {
mv2ok = true;
} else {
mv2ok = false;
}
for (i = 0; i < j_cdb.length; ++i) {
if (j_cdb[i]['cid'] == pid) { // show last item selected
document.getElementById("lastitem").innerHTML = j_cdb[i]['name'];
lstcid = j_cdb[i]['cid']; // remember the cid
}
if (cl[1] <= 4) {
if (j_cdb[i]['pid'] == pid) {
foo = liproto.replace('_CID_', j_cdb[i]['cid'] + '.' + lvl);
foo = foo.replace('_NAME_', j_cdb[i]['name']);
temp += foo;
}
}
}
var l = "l" + cl[1];
document.getElementById(l).innerHTML = temp;
for (i = cl[1] + 1; i < 5; ++i) {
var l = "l" + i;
document.getElementById(l).innerHTML = '';
}
}
$(document).ready(function() {
toJstring();
filllvl('0.0'); //set main level items
});
