Hi guys,

what i have is a textfield which would have a date put in it.  i also have a check box which will represent todays date  <?php date("d/m/y "); ?>

what i would like is if the text field is blank and the checkbox is checked when the submit button is pressed, todays date is submitted to a mysql table.  if the text field is blank and the check box is unchecked, i would like an error to appear.  

any ideas where i can find something like this?

all advice is appreciated

kind regards

jack

The following code will get you started.  Let me know what more you need from there!

Note:  No need to pass the current date as the value of your checkbox since you can just compute it when you process the form data.

<input type="checkbox" id="noDate" value="1"/>
<input type="checkbox" id="myDate" />
 
<?php
 
if(isset($_REQUEST['noDate'])) {
   $myDate = date("m/d/y");
} elseif(isset($_REQUEST['myDate']) && $_REQUEST['myDate']<>"") {
   $myDate = $_REQUEST['myDate'];
   //error checking here to make sure
   //  submission is valid date
} else {
   //give them an error message
}
 
//insert $myDate into your database

Sorry, missed my closing php tag (?>), but you get the idea. :-)

First, change your checkbox value to a "constant value" such as "1" for example. We will do the date derivation in the processing page.

I have two strategies for you:
// REPLACE
// $_POST['textdate'] with your textbox variable
// $_POST['checkdate'] with your checkbox variable
 
// strategy 1 - check both values
// only make date today only if checkbox is checked only if textbox is blank
if ($_POST['checkdate'] == "1"){
 if(isset($_POST['textdate'])){
 
 }
 else
 {
  $zdate = date("d/m/y ");
 }
}
else 
{
 if(isset($_POST['textdate'])){
  $zdate = $_POST['textdate'];
 }else{
  // error both inputs are blank
 }
}
 
 
 
 
 
// strategy 2 - overwrite
// overwrite when checkbox is "checked" no matter what is in textbox
if ($_POST['checkdate'] == "1"){
 $zdate = date("d/m/y ");
else {
 if(isset($_POST['textdate'])){
  $zdate = $_POST['textdate'];
 }else{
  // error both inputs are blank
 }
}

Oops use this instead. Don't forget to change your checkbox value to "1"

 
 
// REPLACE
// $_POST['textdate'] with your textbox variable
// $_POST['checkdate'] with your checkbox variable
 
// strategy 1 - check both values
// only make date today only if checkbox is checked only if textbox is blank
if ($_POST['checkdate'] == "1"){
 if(isset($_POST['textdate'])){
  $zdate = $_POST['textdate'];
 }
 else
 {
  $zdate = date("d/m/y ");
 }
}
else 
{
 if(isset($_POST['textdate'])){
  $zdate = $_POST['textdate'];
 }else{
  // error both inputs are blank
 }
}
 
 
 
 
 
// strategy 2 - overwrite
// overwrite when checkbox is "checked" no matter what is in textbox
if ($_POST['checkdate'] == "1"){
 $zdate = date("d/m/y ");
else {
 if(isset($_POST['textdate'])){
  $zdate = $_POST['textdate'];
 }else{
  // error both inputs are blank
 }
}
