Hello, I am new to php code (month or so) and mysql, I am pretty much teaching myself, I am good with HTML, CSS, JS, etc...
I am trying to create a DB for a client that is fairly simple; Add members (got that done); Verify member and post data below form when queried (Got that done) But the update process has been giving me MAJOR headaches...
The database is as follows:
Set up a test DB on my local server...
the DB = 'cannameds
the table = 'members'
right now I am only testing the first name field which = "first_name" but also have in the table "members":
-'last_name'
-'dob_month'
-'dob_day'
-'dob_year'
-'id_number'
-'exp_month'
-'exp_day'
-'exp_month'
-'notes'
Here is the field info on the table...
id: int(11) - - - no null - no default - auto_increment
first_name: varchar(25) - utf8-general_ci
last_name: varchar(25) - utf8-general_ci
dob_month: varchar(10) - utf8-general_ci
dob_day: varchar(10) - utf8-general_ci
dob_year: varchar(10) - utf8-general_ci
id_number: varchar(50) - utf8-general_ci
exp_month: varchar(10) - utf8-general_ci
exp_day: varchar(10) - utf8-general_ci
exp_year: varchar(10) - utf8-general_ci
notes: varchar(200) - utf8-general_ci
Here is the code I was trying but it does not update but also returns no errors, also when I put the raw data into the query UPDATE line it works but when I use the variables I have assigned it does not update...
I'm sure I have this all wrong as I am so new to php:
edit.php:
PHP Code:
<?php
include 'functions.php';
echo render_header();
echo render_nav();
echo render_query_form();
$submit = $_POST['submit'];
$id_number = trim(strip_tags($_POST['id_number']));
if($submit)
{
$connect = mysql_connect("localhost","root","root");
mysql_select_db("cannameds");
$membercheck = mysql_query("SELECT id_number FROM members WHERE id_number ='$id_number'");
$count = mysql_num_rows($membercheck);
if ($count!=0)
{
mysql_close($connect);
$connect = mysql_connect("localhost","root","root");
mysql_select_db('cannameds') or die( "ERROR: Unable to select database<br />Check to make sure you have a proper connection to your database!>");
$query = "SELECT * FROM members WHERE id_number ='$id_number'";
$result = mysql_query($query);
$num = mysql_numrows($result);
mysql_close();
$i=0;
while ($i < $num) {
$last_name = mysql_result($result,$i,"last_name");
$first_name = mysql_result($result,$i,"first_name");
$dob_month = mysql_result($result,$i,"dob_month");
$dob_day = mysql_result($result,$i,"dob_day");
$dob_year = mysql_result($result,$i,"dob_year");
$id_number = mysql_result($result,$i,"id_number");
$exp_month = mysql_result($result,$i,"exp_month");
$exp_day = mysql_result($result,$i,"exp_day");
$exp_year = mysql_result($result,$i,"exp_year");
$notes = mysql_result($result,$i,"notes");
$link=mysql_connect("localhost", "root", "root");
mysql_select_db("cannameds") or die("unable to connect");
$x = $_GET['first_name'];
$result=mysql_query("SELECT * FROM `members` WHERE first_name='$x'") or die("ERROR:".mysql_error());
$row=mysql_fetch_array($result,MYSQL_ASSOC); //since it returns only 1 row.
echo "$first_name $last_name ";
echo 'is a member.</h2></div><br />';
echo '<form method="POST" name="edit_form" action="update.php"';
echo '<input size="10" class="form_field" type="hidden" value='.$x.' name="old_name" />';
echo 'Change Name? <input size="10" class="form_field" type="text" value="'.$first_name.'" name="first_name" />';
echo '<input name="submit" type="submit" value="Update" />';
$i++;
}
}
else
{
die ("<h3>Patient does not exist in database.</h3>");
}
}
function render_query_form()
{
$output = "
<html>
<form action='edit.php' method='post'>
<span><strong> Edit Patients Information.<br />Please enter the patients Clinic & Dr. ID Number : </strong></span><input class='form_field' type='text' value='' name='id_number' /><br />
<input class='search_btn' type='submit' name='submit' value='search' />
</form>
</html>";
return $output;
}
Second page...
update.php:
PHP Code:
<?php
include 'functions.php';
echo render_header();
echo render_nav();
$link=mysql_connect("localhost", "root", "root");
mysql_select_db("cannameds") or die("Unable to select table!".mysql_error());
$old_name=$_POST['old_name'];
$new_name=$_POST['first_name'];
// "UPDATE `cannameds`.`members` SET `first_name` = \'Dale\' WHERE `members`.`id` = 1;";
mysql_query("UPDATE `cannameds`.`members` SET `first_name` = '$new_name' WHERE first_name='$old_name';") or die("ERROR:".mysql_error());
echo "You have updated $new_name's information. <a href='verify.php' title='go back to the verification page!'>Click here</a> to return to the verification page!";
mysql_close($link);
?>
Any help would be thoroughly appreciated, any suggestions for better code or heck a complete rebuild of the entire structure, I just need to get this code finished 3 days banging head against the wall ARGGGGHHHHH!
