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

 }

}
