Javascriptem może jeśli to kliencka app w przeglądarce? W php to najprościej cURL (albo fsockopen).
Kawałe kodu do JS (wymaga jQuery), nieco skróciłem aby nie zamazać obrazu całości zbędnym kodem:
Kod
function saveNews() {
if($("#form_news_id").val() == '') { $("#form_news_id").val('0'); } //Add news if id empty - just for 100% sure of id
var id = $("#form_news_id").val();
var title = $("#form_title").val();
var content = $("#form_content").val();
var commentsChBox = $('#comments_checkbox').attr('checked');
dataForSave = {"command":"saveNews", "params":{"id":id, "title":title, "content":content, "comments_chbox":commentsChBox}};
postJSON("pages/ajax.news.php", dataForSave, function(data) {
msg_content(data["code"], data["desc"]);
if(data["data"]=="true") { showFilteredNewsTable(); } //If user can correct produced error do not reaload table
}, function(data) {
msg_content("err", "error");
});
}
funkcja postJSON:
Kod
function postJSON(url, data, ok, err) {
if(url=="undefined") { alert('Incorrect call to postRequest() - aborting [no url?]'); return false; }
if(data=="data") { alert('Incorrect call to postRequest() - aborting [no data?]'); return false; }
if(ok=="undefined") { ok = function(data){return;}; }
if(err=="undefined") { err = function(){return;}; }
var ok = ok;
var err = err;
$.ajax({
type: 'POST',
url: url,
data: {"request":$.toJSON(data)},
success: ok,
error: err,
dataType: "json"
});
}
biblioteka implementująca $.toJSON (konwersja tablicy na JSON`a):
Kod
(function($){$.toJSON=function(o)
{if(typeof(JSON)=='object'&&JSON.stringify)
return JSON.stringify(o);var type=typeof(o);if(o===null)
return"null";if(type=="undefined")
return undefined;if(type=="number"||type=="boolean")
return o+"";if(type=="string")
return $.quoteString(o);if(type=='object')
{if(typeof o.toJSON=="function")
return $.toJSON(o.toJSON());if(o.constructor===Date)
{var month=o.getUTCMonth()+1;if(month<10)month='0'+month;var day=o.getUTCDate();if(day<10)day='0'+day;var year=o.getUTCFullYear();var hours=o.getUTCHours();if(hours<10)hours='0'+hours;var minutes=o.getUTCMinutes();if(minutes<10)minutes='0'+minutes;var seconds=o.getUTCSeconds();if(seconds<10)seconds='0'+seconds;var milli=o.getUTCMilliseconds();if(milli<100)milli='0'+milli;if(milli<10)milli='0'+milli;return'"'+year+'-'+month+'-'+day+'T'+
hours+':'+minutes+':'+seconds+'.'+milli+'Z"';}
if(o.constructor===Array)
{var ret=[];for(var i=0;i<o.length;i++)
ret.push($.toJSON(o[i])||"null");return"["+ret.join(",")+"]";}
var pairs=[];for(var k in o){var name;var type=typeof k;if(type=="number")
name='"'+k+'"';else if(type=="string")
name=$.quoteString(k);else
continue;if(typeof o[k]=="function")
continue;var val=$.toJSON(o[k]);pairs.push(name+":"+val);}
return"{"+pairs.join(", ")+"}";}};$.evalJSON=function(src)
{if(typeof(JSON)=='object'&&JSON.parse)
return JSON.parse(src);return eval("("+src+")");};$.secureEvalJSON=function(src)
{if(typeof(JSON)=='object'&&JSON.parse)
return JSON.parse(src);var filtered=src;filtered=filtered.replace(/\\["\\\/bfnrtu]/g,'@');filtered=filtered.replace(/"[^"\\\n\r]*"|true|false|null|-?\d+(?:\.\d*)?(?:[eE][+\-]?\d+)?/g,']');filtered=filtered.replace(/(?:^|:|,)(?:\s*\[)+/g,'');if(/^[\],:{}\s]*$/.test(filtered))
return eval("("+src+")");else
throw new SyntaxError("Error parsing JSON, source is not valid.");};$.quoteString=function(string)
{if(string.match(_escapeable))
{return'"'+string.replace(_escapeable,function(a)
{var c=_meta[a];if(typeof c==='string')return c;c=a.charCodeAt();return'\\u00'+Math.floor(c/16).toString(16)+(c%16).toString(16);})+'"';}
return'"'+string+'"';};var _escapeable=/["\\\x00-\x1f\x7f-\x9f]/g;var _meta={'\b':'\\b','\t':'\\t','\n':'\\n','\f':'\\f','\r':'\\r','"':'\\"','\\':'\\\\'};})(jQuery);
