PHP - Moved: Generating A Password Without The Letters 'oh' Or 'el' Or The Numbers 1 Or 0

Can I somehow mix letters with numbers to create an array with range()?

e.g. I want my array for postcode ranges such as array('AB1','AB2', 'AB3', 'AB4', 'AB5', 'Ab6', 'AB7', 'AB8', 'IV5', 'IV6', 'IV7', 'IV8', 'IV9', 'IV10');

I know I can do range(1,8); but was wondering if there was something along the lines of range("AB1", "AB8");

I need users to input ONLY  numbers or letters with numbers.  How can i go about fixing that.


Thank you.

Here is my code

if(isset($_POST['pass_btn']))
{
    $numchars = 8;
    $chars = explode(',','2,3,4,5,6,7,8,9,a,b,c,d,e,f,g,h,i,j,k,m,n,p,q,r,s,t,u,v,w,x,y,z,2,3,4,5,6,7,8,9,A,B,C,D,E,F,G,H,J,K,L,M,N,P,Q,R,S,T,U,V,W,X,Y,Z,2,3,4,5,6,7,8,9');
    $password='';
        for($i=0; $i<$numchars;$i++)
        {
            $password.=$chars[rand(0,count($chars)-1)];
        }
}

This is set up so when a person pressing the pass_btn, a password is provided.  This works just fine.  However, it refreshes the page and clears all other data that user may have entered.

Suggestions?

Hi all,

I have a form includes fields of customer id and Account type( stored in a jump menu and includes 6 different types of accounts)


<style type="text/css">
<!--
body,td,th {
font-size: 18px;
font-weight: bold;
}

</style>
<p><img src="../images/mahapitiya 1.jpg" width="1024" height="139" /></p>
<form id="form1" name="form1" method="post" action="">
  <label>
    <input type="submit" name="button" id="button" value="Logout" />
  </label>
</form>
<p>&nbsp;</p>
<form action="" method="post" name="form2" id="form2" 
onsubmit="return Validate();">
  <fieldset>
    <legend class="cap">Create an Account</legend>
    <table width="75%" border="0" cellspacing="0" cellpadding="5" align="center">
      <tr>
        <td>&nbsp;</td>
        <td class="title02">&nbsp;</td>
        <td>&nbsp;</td>
        <td>&nbsp;</td>
      </tr>
      <tr height="30">
        <td width="10%">&nbsp;</td>
        <td width="25%" class="title02" align="left">Customer ID</td>
        <td width="55%" class="attribute1" align="left"><input type="text" name="customer_id" class="attribute1" /></td>
        <td width="10%">&nbsp;</td>
      </tr>
      <tr height="30">

        <td width="25%" class="title02" align="left">Account Type</td>
        <td width="55%" align="left" bgcolor="#FFFFFF" class="attribute1"><select name="account_type" id="jumpMenu" >
            <option selected="selected"></option>
            <option>Savings Investment</option>

          </select>&nbsp;</td>
        
        <td width="10%">&nbsp;</td>
      </tr>
    </table>
    <p align="center">&nbsp;</p>
    <p align="center">
      <input type="submit" onclick="return Validate();" name="submit" value="Submit" class="attribute1" />
      &nbsp;&nbsp;
      <input type="reset" name="reset" value="Reset" class="attribute1" />
      &nbsp;&nbsp;
      <label>
        <input type="submit" name="button2" id="button2" value="Help" />
      </label>
    </p>
  </fieldset>
  </td>
  <td width="5%">&nbsp;</td>
  </tr>
  <tr>
    <td>&nbsp;</td>
    <td>&nbsp;</td>
    <td>&nbsp;</td>
  </tr>
  <tr>
    <td>&nbsp;</td>
    <td align="center">&nbsp;</td>
    <td>&nbsp;</td>
  </tr>
  <tr>
    <td>&nbsp;</td>
    <td><font color="red" size="1" ></font></td>
    <td>&nbsp;</td>
  </tr>
  </table>
</form>
<p>&nbsp;</p>

<script language = "Javascript">
  
function Validate()
{
    if (document.form2.customer_id.value == '') 
    {
        alert('Please enter the valid customer id!');
        return false;
}
else if ( document.form2.account_type.selectedIndex == '' )
    {
        alert ( "Please select an account type!." );
        return false;
    }
return true;
}
</script>



There are 6 different types of tables exist in my database representing 6 different types of accounts.Each and every table there is a field called "account number" which is auto incremented.When user clicks on submit button i want account number to be opened based on selected account type.

How this could be done?

Thanks,
Heshan.
