JavaScript - Why Is Javascript Corrupting My Php Script?
Hello all,
I'm new to PHP (and web development in general) and have come across something that to me seems really, really bizarre! Background I am currently designing and developing an online enrolment form for my employer, a training company. The form consists of 3 pages - pages 1 and 2 are for data input whilst page 3 is a summary page with only one input, a box to check that the customer agrees to our T&Cs. Page 3 also includes a box where calculations are made as to the price of the selected training course based on choices made earlier in the form. The form displayed on page 2, and some of the text on page 3, changes depending on a choice made on page one - that is, whether they are paying for the course themselves or their employer is funding it. If they choose employer, they get one form, if they choose self funding they get a different one. However, both of these forms are contained within a single .php file, using session variables to decide which one should be displayed. I am using sessions to transfer the data between the pages. Each page has been made sticky using session variables. Real-time validation is carried out using javascript on each individual page, then a final PHP validation check is run on the whole thing when the customer tries to submit the final page. Javascript is also used on page one to calculate the price of the course in real time so the customer can see how much he/she will be paying before proceeding further. The Problem I find this really strange: In Firefox, everything works perfectly In Internet Explorer, when JavaScript is turned off, everything is fine. But when JS is switched on, the PHP validation on the final page seems to go haywire, thus making it impossible to submit the form. In Chrome, again when JS is switched off, everything works, but when switched on, I can't even get past the first page. Instead of loading the correct form for page 2, I just get a blank screen. Can anyone help? This is my first major project and I've been working on it for weeks, coming up against all sorts of problems and tearing my hair out but managing to solve them. Now I'm completely stumped, when I'm almost within touching distance of completion!! I can't post the code here as it's 3 separate documents and very complicated, but if you want to have a look at the form itself go to: http://testing.xenongroupadmin.com/t.../enrolment.php I hope someone can help! Thanks very much! All the best Chris Similar TutorialsHi, I was wondering how to load an external .php script file in javascript, and make use of a php variable in the javascript. Thanks in advance. EDIT: If this is not possible, is there some way to send the php data to the javascript by using php, and then accessing the data that was sent in the javascript, and making use of it? What I'm trying to do is get a OpenTok session id from a .php script to javascript. Hi, I have a a-z brand menu on my site. I want the user to be able to select a letter and a list of brands appear. The problem I have is that I want the layer to appear at the position of the mouse (from the top left). I have this working fine but then when you rollover a link (brand) within the layer div it reactivates the call command and re positions the layer to the mouse again. Please Please help. My code is as follows; POSITION CODE; Code: var cX = 0; var cY = 0; var rX = 0; var rY = 0;
function UpdateCursorPosition(e){ cX = e.pageX; cY = e.pageY;}
function UpdateCursorPositionDocAll(e){ cX = event.clientX; cY = event.clientY;}
if(document.all) { document.onmousemove = UpdateCursorPositionDocAll; }
else { document.onmousemove = UpdateCursorPosition; }
function AssignPosition(d) {
if(self.pageYOffset) {
rX = self.pageXOffset;
rY = self.pageYOffset;
}
else if(document.documentElement && document.documentElement.scrollTop) {
rX = document.documentElement.scrollLeft;
rY = document.documentElement.scrollTop;
}
else if(document.body) {
rX = document.body.scrollLeft;
rY = document.body.scrollTop;
}
if(document.all) {
cX += rX;
cY += rY;
}
d.style.left = (cX+5) + "px";
d.style.top = (cY+5) + "px";
}
TOGGLE HIDE SHOW LAYER; Code: function toggle_visibility(id) {
var e = document.getElementById(id);
AssignPosition(e);
if(e.style.display == 'block')
e.style.display = 'none';
else
e.style.display = 'block';
}
EXAMPLE OF A-Z MENU; Code: <a href="#" onclick="toggle_visibility('uniquename0');">A</a>
EXAMPLE OF LAYER TO DISPLAY WHICH CONTAINS THE OFFENDING LINKS; Code: <div id="uniquename0" style="border-style: solid; padding: 5px; display: none; position: absolute; background-color: white; left: 482px; top: 428px;" onmouseout="toggle_visibility('uniquename0');">

Thank you Dan Hi, I am trying to add one image in footer of my application. Code: <div class="rightLinks"> <a href="#"><script src=https://seal.somesign.com/getseal?host_name=www.validsite.com&size=S&use_flash=NO&use_transparent=NO&lang=en></script></a> </div> But this is not working. Please let me know, what is wrong in it. And how can we correct it. Thanks!! Regards, Neha Hello everyone, I have setup a script called Uploadify it is a basic file uploader script however by default it does not show a link to the uploaded file. I have had to look in the documentation on to do this but there is no clear guide on how to do it. I found this function though which I belieave is the solution: http://www.uploadify.com/documentati.../oncomplete-2/ Here are the functions I am using: Code: 'onComplete' : function(event, ID, fileObj, response, data) {
document.write('http://www.cqwebdesign.co.uk' + fileObj.filePath +'');
}
This works kinda but when it shows the link the page continues loading as if it is stuck in some loop? You can try it out he http://www.cqwebdesign.co.uk/SC2/index.html Thanks I have an age script running in the attachment below. It works fine for numbers such as 1 22 1980. Code: if ((input.search(/\b([1-9]|[12][0-9]|3[01])\b/)!= -1) && (input.search(/\b([1-9]|1[0-2])\b/)!=-1) && (input.search(/\b(19[0-9]{2}|200[0-9]|201[01])\b/)!= -1)) {
function getBirth() {
var now = new Date();
var myMatchy = input.match(/\b(19[0-9]{2}|200[0-9]|201[01])\b/);
var myMatchm = input.match(/\b([1-9]|1[0-2])\b/)
var myMatchd = input.match(/\b([1-9]|[12][0-9]|3[01])\b/);
var year = myMatchy[0];
var month = myMatchm[0];
var day = myMatchd[0];
var today =
{
"year" : now.getFullYear(),
"month": now.getMonth()+1,
"day" : now.getDate()
}
var age = today["year"] - year;
if (month > today["month"])
age--;
else if (month == today["month"])
if (day > today["day"]) age--
return age;
}
document.result.result.value = "Your age is "+getBirth()+".";
return true;}
However, if someone writes out the month it doesn't. Such as January 22 1980. I did a work-around by inserting the month value. Highlighted below. But that means I would have to duplicate this lengthy code 12 times for each month of the year. Anybody know a better way to handle this? You can test it in the small attachment below. Any help would be appreciated. Code: if ((input.search(/\b([1-9]|[12][0-9]|3[01])\b/)!= -1) && (input.search(/(january)/)!= -1) && (input.search(/\b(19[0-9]{2}|200[0-9]|201[01])\b/)!= -1)) {
function getJan() {
var now = new Date();
var myMatchy = input.match(/\b(19[0-9]{2}|200[0-9]|201[01])\b/);
var myMatchd = input.match(/\b([1-9]|[12][0-9]|3[01])\b/);
var month = 0;
var year = myMatchy[0];
var day = myMatchd[0];
var today =
{
"year" : now.getFullYear(),
"month": now.getMonth()+1,
"day" : now.getDate()
}
var age = today["year"] - year;
if (month > today["month"])
age--;
else if (month == today["month"])
if (day > today["day"]) age--
return age;
}
document.result.result.value = "Your age is "+getJan()+".";
return true;}
Hi peeps I found this script on another forum, It is nearly perfect, I was wondering if you peeps could help me make a few changes... how do I change the cut off to 8pm I have tried var c_t = 8; but it does 8am I have also tried var c_t = 20; but it doesnt work... Any ideas? Also instead of just saying "your order will ship shifted to tommrow" would it be possible to insert tomorrows date, i.e Thursday 13th and then for "and your order will ship to Monday" could it say Monday 15th etc Here is the script, Code: <html>
<head>
<script type="text/javascript">
function ord()
{
var c_t = 4;
var dd = new Date();
var ti_h = dd.getHours();
var ti_m = dd.getMinutes();
if(ti_h > c_t)
{
var di_t_h = ti_h - c_t;
var di_t_mi = 60 - ti_m;
var h = 24 - di_t_h;
var mi = di_t_mi;
var mess = h+"hours"+mi+"minutes";
}
var da = dd.getDay();
//var da = document.getElementById("da").value;
switch(da)
{
case 2:
case 3:
case 4:
case 5:
document.write("Place your order within the next 1 day"+mess+"and your order will ship shifted to tommrow");
break;
case 6:
case 7:
case 1:
document.write("and your order will ship to Monday");
break;
}
}
ord();
</script>

Coding a refresh button, for instance. How would I go about doing this? Thank you in advance. Hi, I have a little problem with placing a javascript into a php script If the action "Change" is true then I want to open a new window with a javascript below. I get an error message: Parse error: syntax error, unexpected '<' in /home/........ on line xx On that xx line starts the Javascript What must I do to solve this problem. <?php.................... if($_REQUEST['action']=="Change") { mysql_query("UPDATE Persons SET Itemstate = '{$_REQUEST['Nr']};' WHERE Nr={$_REQUEST['Nr']};"); <SCRIPT LANGUAGE="javascript"> <!-- window.open ('Examplepage.html') --> </SCRIPT> ........ ?> I have a Perl script that contains a variety of inputs including a HTML <SELECT> and RADIO buttons. I would like to alter the presentation of a RADIO button choice with a DISABLED, based upon the earlier selection of from a <SELECT> drop down menu. In Perl I attempted to capture the selection from the <SELECT> and use that value in a IF ELSE block, but this does not work. I have been told that this can be done with a Javascript. I did a little bit of coding with Javascript around five years ago, so I am a rusty newbie. Can anyone give me a hand on how this should be constructed? The more detailed your examples or suggestions can be the easier it will be for me to grasp the solution. Hi they all, I want make autocompleted searching for my site.

Is there a way to use inline javascript that will prevent any javascript after it (in the same page) from executing? So, for instance I could have something like: -Content- -JS A- -Content- -JS B- -JS C- 'JS A' would execute, 'JS B' would be the code I'm asking about and it would cause 'JS C' to not do anything. Sorry if this is an off-the-wall question. I good with C/C++, VB, Ruby, Lua, HTML, etc, but I haven't gotten to Javascript (or Java) yet so I have no idea what the capabilities or environment setup are like. Thanks in advance for any advice. I am really new to JavaScript, and was following a tutorial that was using everything inline (probaby as its less confusing for the noob). Now I want to split it off into a script area, like my CSS has been. I have: Code: <SPAN onclick="document.getElementById('glance').style.display='block';document.getElementById('front').style.display='none';">
Is something like this valid (this is a guess BTW)? Code: <SCRIPT type="text/javascript">
function getElementById('glance') {
.style.display='block';
}
function getElementById('front') {
.style.display='none';
}
</SCRIPT>
<SPAN onclick="document.getElementById('glance'); document.getElementById('front')"> ... </SPAN>
... or should function be document in the script area and document not be present in the SPAN attribute? ... Better yet, is there a way to put both the 'glance' and 'front' together like this: Code: <SCRIPT type="text/javascript">
function getElementById ('glance') {
.style.display='block';
getElementById ('front') {
.style.display='none';
}
}
</SCRIPT>
I am in the process of making a website and have a question as I am new to javascript, for the smaller screens I would like to have a script that moves the link buttons closer together and resizes them to make them smaller. Is this possible and if so can someone write the code for me to then alter for the website. The website is tvbcraft.com and it is the menu bar i am trying to add a script to. The buttons have a menustyle.css sheet and a menuscript.js file.
Hi, Im new to javascript. I want to add a similar function on my blog like on http://techcrunch.com/2011/08/04/gro...tartup-obtiva/ when you press on author. It is a drop down made with javascript. Anybody can help with a similar javascript as I was trying different implementations for the whole night with no luck. Maybe, anybody know a similar javascript online which I could modify? Thanks in advance! Hi all Experts I am in a need of a simple javascript script that can verify if a cokie exist If it exist: (replace the below and show) You already upgraded. If not exist: I would like it to show: You account is not upgraded yet Please upgrade your account, click here to upgrade<br> <center><A href="url"><img src="picture"></center> also need seperate script to set the cokie Hope u understand what I want thank you I'm trying to built a simple Javascript page that will serve the purpose of merging the values inputted into a form, and then using concatenation to merge these values in with other text to form several lines of commands that would be entered into a router to perform some task. So in other words, it's just a "Merge" script. I should mention that I'm just starting to learn Javascript. I actually haven't been finding Javascript as easy as I thought it would be to learn, and I think it's because there are several ways to do the same thing and I wouldn't be surprised if my problem is I'm using two different methods here...or just using the completely wrong method.... I've seen examples of using 'for' loops and arrays in forms, and I still can't get my head around that. If possible for now I just wish to call in the values and concatenate them, but maybe I do need a loop I don't know Anyway, at this point, my only wish is to be able to get the script to concatenate the values, and then later I'll add the rest of the text it will merge in with and have it write to the page instead of the console. So here is what I have right now. It only partially works (I'm only writing to the console in FireFox at the moment to debug while I test, so that is why you see console.log instead of document.write or whatever. There are 4 fields in the form, and for example, if I enter in each field one word: This is a test The ONLY result I get when submitting the form is the word "This". Then the form is cleared out of all values that were entered. I'd like it to grab all the values at once but that isn't happening. Also, you'll notice I have some 'var' statements commented out. I was trying to use them so that I can later shortcut my script by concatenating using a shorter variable. (ie - using the variable 'cluster' instead of 'document.forms.myForm.cluster.value' when I'm writing the rest of the script). However something isn't right as no matter where I try putting the var statements I get errors that those variables are undefined. I even tried defining them at some point first with some random value but that didn't help either), so that's why I commented them out for now. anyway, here is my feeble attempt at writing this script, any help or guidance would be much appreciated. Code:
<!DOCTYPE html PUBLIC "-//WC3//DTD XHTML 1.0 Transitional//EN">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>Router Subnet Commands</title>
</head>
<body bgcolor="#FFFFFF">
<script language="Javascript" type="text/javascript">
//var cluster = document.forms.myForm.cluster.value;
//var subnetip = document.forms.myForm.subnetip.value;
//var routerip = document.forms.myForm.routerip.value;
//var cidr = document.forms.myForm.cidr.value;
function merge() {
console.log(document.forms.myForm.cluster.value) + console.log(document.forms.myForm.subnet.value) + console.log(document.forms.myForm.router.value) + console.log(document.forms.myForm.cidr.value);
}
</script>
<form id="myForm">
<input name="cluster" id="cluster"/> cluster number <p>
<input name="subnetip" id="subnetip"/> subnet IP address <p>
<input name="routerip" id="routerip"/> router IP address<p>
<input name="cidr" id="cidr"/> CIDR <p>
<input type="submit" value="Get Commands" onclick="merge()" />
</form>
</body>
</html>
Any advice would be much appreciated. Thanks Nat Hello, I need help again :3 Heres what I need: I need some javascript to random a script. Simply like this: The script randoms a number Based on the number it runs some lines of PHP script. Random 1-10 If 1 Then run this PHP script *PHP script* *PHP script* *PHP script* *PHP script* If 2 Then run this PHP script *Different PHP script* *Different PHP script* *Different PHP script* *Different PHP script* If 3 Then run this PHP Script *some more different PHP Script* *some more different PHP Script* *some more different PHP Script* *some more different PHP Script* If 4 etc etc etc Each bit of PHP Will be similar, but be different in some ways. There may be more compressed ways of doing this. But if it at all possible, I would like it in the way I wrote it above. For instance I dont want: Random 1-3 If 1 Run function 1 If 2 Run function 2 If 3 Run function 3 Function 3 *PHP Script* *PHP Script* *PHP Script* Function 1 *PHP Script* *PHP Script* *PHP Script* Function 2 *PHP Script* *PHP Script* *PHP Script* I will thank the best answer! This website is awesome and has answered so many of my questions! Thanks in advance! I have a webpage in which my users complete a form in order to get through to page 2. I cannot use PHP to check as it must be on-the-fly checking. My idea was like the following: PHP Code: <script type="text/javascript"> function check(x) { if (x == 1) { document.write('<IMG SRC="img/'+x+'.jpg">'); } if (x == 2) { document.write('<IMG SRC="img/'+x+'.jpg">'); } if (x == 3) { document.write('<IMG SRC="img/'+x+'.jpg">'); } if (x == 4) { document.write('<IMG SRC="img/'+x+'.jpg">'); } } </script> And for the images to actually be PHP files that check further details of the user and insert details to DB. Then when the user clicks the next button it will check to see if all 4 users have loaded under that users details. However, I would much prefer it if I could use more PHP as I'm a Javascript n00b. Preferably I would like to use PHP to create unique keys for the images so that once I have obfuscated the javascript code the user will not figure out how to cheat the system even if they manage to reverse engineer the code. Is it possible to use PHP within javascript? E.g. PHP Code: <?php $pic = "picture.jpg"; ?> <script> function something(){ document.write('<IMG SRC="img/$pic">'); } </script> Or is this not at all possible? Edit: I know how much simpler that first script could have been, was just trying to simplify from my double as messy full script which will probably confuse you even more!!! |
