Hey je suis donc très nouveau pour PHP, mais l'apprentissage et je suis en train de faire un simple contact de nous forum dans lequel l'utilisateur remplit les champs et il les courriels des champs à une adresse e-mail. Le seul problème est que je ne connais pas un bon moyen de vérifier tous mes champs pour les caractères invalides / champs vides. Voici ce que j'ai si loin que ne me donne rien:
Code: [ Select ]
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
</head>
<body>
<script language="Javascript">
function doClear(Text) {
   if(Text.value == Text.defaultValue) {
     Text.value = ""
   }
}

</script>
<h3>Leave a comment for us!</h3>
First Name: <br />
<input name="Fname" type="text"> <br />
Domain name: <br />
<input name="Domain" type="text"> <br />
Comments: <br />
<textarea name="Comments" cols="21" rows="6" wrap="hard" onFocus="doClear(this)">Please insert your comments here...</textarea> <br />
<?php
function check($msg)
{
  echo "<script langauge=\"Javascript\">alert(\"".$msg."\");</script>";
}
?>
<input type="submit" name="submit" value="Submit" onFocus="<?php $name = Fname; if(strlen($name) == 0) { check("aaa"); }?>" />
</h3>
</body>
</html>
  1. <html>
  2. <head>
  3. <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
  4. </head>
  5. <body>
  6. <script language="Javascript">
  7. function doClear(Text) {
  8.    if(Text.value == Text.defaultValue) {
  9.      Text.value = ""
  10.    }
  11. }
  13. </script>
  14. <h3>Leave a comment for us!</h3>
  15. First Name: <br />
  16. <input name="Fname" type="text"> <br />
  17. Domain name: <br />
  18. <input name="Domain" type="text"> <br />
  19. Comments: <br />
  20. <textarea name="Comments" cols="21" rows="6" wrap="hard" onFocus="doClear(this)">Please insert your comments here...</textarea> <br />
  21. <?php
  22. function check($msg)
  23. {
  24.   echo "<script langauge=\"Javascript\">alert(\"".$msg."\");</script>";
  25. }
  26. ?>
  27. <input type="submit" name="submit" value="Submit" onFocus="<?php $name = Fname; if(strlen($name) == 0) { check("aaa"); }?>" />
  28. </h3>
  29. </body>
  30. </html>

Voici la validation js et la forme que j'ai utilisé auparavant.

Validation
Code: [ Select ]
<script type="text/JavaScript" language="JavaScript">
<!--
function validateForm()
{
var invalid = " ";
var name = document.form1.name.value;
var subject = document.form1.subject.value;
var emailAddress = document.form1.email.value;
var emailAddressVerify = document.form1.emailc.value;

if (name == ""){
    alert("You must indicate your name");
    return false;
  }
if (emailAddress == ""){
    alert("You must enter your email address");
    return false;
  }
if (subject == "clear"){
    alert("You must select a subject");
    return false;
  }
if (document.form1.email.value.indexOf(invalid) > -1 || document.form1.emailc.value.indexOf(invalid) > -1){
    alert("No spaces allowed in email address");
    return false;
    } else
    if ( emailAddress != emailAddressVerify ){
        alert("The email addresses do not match");
        return false;
        } else
    if (/^\w+([\.-]?\w+)*@\w+([\.-]?\w+)*(\.\w{2,3})+$/.test(emailAddress)){
        return (true)
        } else
    alert("Invalid E-mail Address! Please re-enter.")
    return (false)
    }

//-->
</script>
  1. <script type="text/JavaScript" language="JavaScript">
  2. <!--
  3. function validateForm()
  4. {
  5. var invalid = " ";
  6. var name = document.form1.name.value;
  7. var subject = document.form1.subject.value;
  8. var emailAddress = document.form1.email.value;

  12.     alert("You must indicate your name");
  13.     return false;
  14.   }
  15. if (emailAddress == ""){
  16.     alert("You must enter your email address");
  17.     return false;
  18.   }
  19. if (subject == "clear"){
  20.     alert("You must select a subject");
  21.     return false;
  22.   }

  26.     } else
  27.     if ( emailAddress != emailAddressVerify ){
  28.         alert("The email addresses do not match");
  29.         return false;
  30.         } else
  31.     if (/^\w+([\.-]?\w+)*@\w+([\.-]?\w+)*(\.\w{2,3})+$/.test(emailAddress)){
  32.         return (true)
  33.         } else
  34.     alert("Invalid E-mail Address! Please re-enter.")
  35.     return (false)
  36.     }
