PHP click for results

Placebo · 21-05-2010 11:28PM #1

lets say database
Baby has 2 results BabyFood and BabyNeeds

anyway on clicking Baby i can show BabyFood and Babyneeds ?

obviously cant use href tag and a php function, silly.
i can think of a silly way of storing the results in an array for all the values in question and upon click showing the particular div, but thats beyond practical and limited dynamic wise.

i could use a form but id have to make all the vales eg:Baby into a button
and i dont want to go to a new page. I.e no page refreshes !?

<B>EDIT:</B>
i have something work with ajax, but only work for a button, can anyone help me manipulate the functions below for it to work for a link? 'aaa'
[PHP]<input type="submit" value="load() GET" id="load_get" />

<A href="" id="load_get">aaa</a>

<div id="result" class="functions">
</div>

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"></script>
<script type="text/javascript">

$.ajaxSetup ({
cache: false
});
var ajax_load = "<img class='loading' src='img/load.gif' alt='loading...' />";

// load() functions
var loadUrl = "load.php";
$("#load_basic").click(function(){
$("#result").html(ajax_load).load(loadUrl);
});

$("#load_get").click(function(){
$("#result")
.html(ajax_load)
.load(loadUrl, "language=php&version=5");

});

// $.get()
$("#get").click(function(){
$("#result").html(ajax_load);
$.get(
loadUrl,
{language: "php", version: 5},
function(responseText){
$("#result").html(responseText);
},
"html"
);
});

</script>[/PHP]

I've never tried it but you can get a link to fire an AJAX request. If the AJAX function is called myAJAXFunction() then simply do this:

<a href="javascript:myAJAXFunction();">link text</a>

Hope that helps but still unsure about what it is you actually want to do. If you can clarify there may be an easier way to do it.

i think for jquery i can just set the id=get
and it will call get click function

basically
i just want a simple javascript/ajax script that pass a variable to a php function

So you want to call that script using a link?

Why don't you use <a href="javascript:myfunction();">my link</a>

Not sure if this will help. I don't use Jquery (really need to start it) but instead direct AJAX which probably isn't the most productive. But anyways something like this...

[ajax.js]

var xmlHttp = createXmlHttpRequestObject();

function createXmlHttpRequestObject()
{
	var xmlHttp;
	try
	{
		xmlHttp = new XMLHttpRequest();
	}
	catch(e)
	{
		var XmlHttpVersions = new Array("MSXML2.XMLHTTP.6.0",
										"MSXML2.XMLHTTP.5.0",
										"MSXML2.XMLHTTP.4.0",
										"MSXML2.XMLHTTP.3.0",
										"MSXML2.XMLHTTP",
										"Microsoft.XMLHTTP");
		for (var i = 0; i < XmlHttpVersions.length && !xmlHttp; i++)
		{
			try
			{
				xmlHttp = new ActiveXObject(XmlHttpVersions[i]);
			}
			catch(e) { }
		}
	}
	if (!xmlHttp)
		alert("Error Creating the XML HttpRequest Object");
		else
			return xmlHttp;
}

function GetNames(babyname, param2)
{
	document.getElementById('babynameresultsdiv').innerHTML='<p>Sending your request...</p>';
	if (xmlHttp)
	{
		try
		{
			
			var divelement = "babynameresultsdiv";
				xmlHttp.open("GET", 'myphpscript.php?babyname='++'&anotherparam='+param2, true);
		
			xmlHttp.onreadystatechange = 
			
			function handleRequestStateChange()
{
	
	myDiv = document.getElementById(divelement);
	if (xmlHttp.readyState == 1)
	{
		myDiv.innerHTML = "<p>Sending your request...</p>";
	}
	else if (xmlHttp.readyState==2)
	{
		myDiv.innerHTML = "<p>Sending your request...</p>";

	}
	else if (xmlHttp.readyState==4)
	{
		if (xmlHttp.status == 200)
		{
			try
			{
				//This is where the output returned from php script will be put in the div
				var response = xmlHttp.responseText;
				myDiv.innerHTML = ""+response+"";
				
			}
			catch(e)
			{
				alert("Error Getting baby names");
			}
		}
		else
		{
		alert("There was a problem retrieving content:\n" + xmlHttp.statusText);
		}
	}
}
			xmlHttp.send(null);
		}
		catch(e)
		{
			alert ("Can't connect to server:\n" + e.toString());
		}
	}
}

[mypage.html]

# Include the js script
# Call the GetNames method using a link with a href = javascript:GetBabyNames()
# Have a div to display content.

might be missing something but can you not use this?

http://api.jquery.com/jQuery.post/

point it towards a php file that grabs the data you pass it and display the results if any?

PHP click for results
