did you forgot the extension of your pic?
try change
Code: Select all
function user($val) {
if (is_numeric($val)) {
echo '<img src="mypic.jpg" />' ;
}
}

i don't think an invalid extension would cause it to render text rather than an empty block level element.
could you post more code?

no i do not think thats because of extension
i do not know why its rendered as a text instead of real tag
this some more part of my code
Code: Select all
function validateRequired($required,$val,$typecheck)
{
// if it is required check to see if it validates
if ($required == "required")
{
if ($val == "")
{
// if val is blank then then the field is invalid
echo "Required";
exit(); //we do not need to check for anything else so exit the validation
}
if ($val !== "" && $typecheck == "none")
{
// if val is not blank and there are no further validation checks ("none") respond with a thank you for feedback
echo "Thank You";
}
}
// if it is not required or typecheck is not none, the script will continue to validate
}
function user($val) {
if (is_numeric($val)) {echo '<img src="mypic" />' ;} }
function validateEmail($val)
{
global $continueSubmit ;
if (ereg ("^([0-9a-zA-Z]+[-._+&])*[0-9a-zA-Z]+@([-0-9a-zA-Z]+[.])+[a-zA-Z]{2,6}$", $val, $regs))
{
echo "Thank You";
}
else
{
$continueSubmit = false;
echo "Invalid Email Address";
}
}
is it possible that cause i do not have <html> and <body> ----</body> </html> in my page this happens ?
and something else i m getting the response back through ajax and innerhtml can it be the reason ?
thanks

What's the extension of your page file? Maybe it's not being parsed through PHP.
Nice nickname btw.

thanks for nickname
the extension is php its parsed correctly
the only thing comes to my mind is cause response is going back through ajax it parses only as simple text and not the image it self
can it be the case and if yes how should i solve it ?

yes sure
this is the whole java codes for ajax usage which capture the form inputs and send to my php script and get the response back
Code: Select all
window.onload = attachFormHandlers;
var gShow; //variable holding the id where feedback will be sent to.
var sUrl = "formvalidation.php?validationtype=ajax&val=";//url is the page which will be processing all of the information. it is important to make sure validationtype is ajax
var gErrors = 0; //number of errors is set to none to begin with
var http = getHTTPObject();
function attachFormHandlers()
{
var form = document.getElementById('form1')
if (document.getElementsByTagName)//make sure were on a newer browser
{
var objInput = document.getElementsByTagName('input');
for (var iCounter=0; iCounter<objInput.length; iCounter++)
objInput[iCounter].onblur = function(){return validateMe(this);} //attach the onchange to each input field
}
form.onsubmit = function(){return validate();} //attach validate() to the form
}
/*validateMe is the function called with onblur each time the user leaves the input box
passed into it is the value entered, the rules (which you could create your own), and the id of the area the results will show in*/
function validateMe(objInput) {
sVal = objInput.value; //get value inside of input field
sRules = objInput.className.split(' '); // get all the rules from the input box classname
sRequired = sRules[1]; // determines if field is required or not
sTypeCheck = sRules[2]; //typecheck are additional validation rules (ie. email, phone, date)
gShow = sRules[3]; //gShow is the td id where feedback is sent to.
//sends the rules and value to the asp page to be validated
http.open("GET", sUrl + (sVal) + "&sRequired=" + (sRequired) + "&sTypeCheck=" + sTypeCheck, true);
http.onreadystatechange = handleHttpResponse; // handle what to do with the feedback
http.send(null);
}
function handleHttpResponse() {
//if the process is completed, decide to do with the returned data
if (http.readyState == 4)
{
sResults = http.responseText.split(","); //results is now whatever the feedback from the php page was
//whatever the variable glo_show's (usermsg for example) innerHTML holds, is now whatever was returned by the php page.
document.getElementById(gShow).innerHTML = "";
document.getElementById(gShow).appendChild(document.createTextNode(sResults[0]));
}
}
function validate()
{
var tables;
tables = document.getElementsByTagName('td')
for (i=0; i<tables.length; i++)//loop through all the <td> elements
{
// if the class name of that td element is rules check to see if there are error warnings
if (tables[i].className == "rules")
{
//if there is a thank you or its blank then it passes
if (tables[i].innerHTML == 'Thank You' || tables[i].innerHTML == '' )
{
tables[i].style.color = '#000000';//the color is changed to black or stays black
}
else
{
gErrors = gErrors + 1; //the error count increases by 1
tables[i].style.color = '#ff0000';//error messages are changed to red
}
}
}
if (gErrors > 0)
{
//if there are any errors give a message
alert ("Please make sure all fields are properly completed. Errors are marked in red!");
gErrors = 0;// reset errors to 0
return false;
}
else return true;
}
function getHTTPObject() {
var xmlhttp;
/*@cc_on
