I am trying to update a mysql database but every time I get the Notice: Array to string conversion. I really can't figure out what I'm doing wrong here. Can someone kindly help?
My form
<div class="panel-body">
<form role="form" method="post" action="client_post.php" class="form-horizontal">
<fieldset>
<div class="form-group">
<label class="col-sm-3 control-label">Hospital No:
</label>
<div class="col-sm-5">
<input required class="form-control" name="Hospital_no" placeholder="Patients' Hospital Number">
</div>
</div>
<div class="form-group">
<label class="col-sm-3 control-label">Date of New Status</label>
<div class="form-group">
<label class="col-sm-3 control-label">New Status</label>
<div class="col-sm-5">
<select required name ="art_status" class="form-control">
<option></option>
<option value = "ART Restart" name="ART Restart">ART Restart</option>
<option value = "ART Transfer Out" name="ART Transfer Out" >ART Transfer Out</option>
<option value = "Pre ART Transfer Out" name="Pre ART Transfer Out">Pre ART Transfer Out</option>
<option value = "Lost to Followup" name="Lost to Followup">Lost to Followup</option>
<option value = "Stopped Treatment" name="Stopped Treatment">Stopped Treatment</option>
<option value = "Known Death" name="Known Death">Known Death</option>
</select>
</div>
</div>
<div class="form-group">
<div class="col-sm-offset-3 col-sm-5">
<input class="btn btn-primary" type="submit" value="Update" name="submit" >
</div>
</div>
</fieldset>
</form>
I'm trying to make the update from this page (client.php)
if($_SERVER['REQUEST_METHOD'] === 'POST')
{
$Hosp_no = ['Hospital_no'];
$art_status = ['art_status'];
$art_date = ['art_start_date'];
$update_client = "UPDATE `pat_reg` SET `art_status` = '$art_status', `art_start_date` = '$art_date' WHERE `Hospital_no` = '$Hosp_no'";
if (mysqli_query($dbcon,$update_client))
{
echo"<script>alert('Record Updated')</script>";
//echo"<script>window.open('client_update.php','_self')</script>";
}
$dbcon->close();
}
Please help.
Using the $_POST
superglobal allows you to access the values submitted in the form.
Change the following:
$Hosp_no = ['Hospital_no'];
$art_status = ['art_status'];
$art_date = ['art_start_date'];
to this:
$Hosp_no = $_POST['Hospital_no'];
$art_status = $_POST['art_status'];
$art_date = $_POST['art_start_date'];
PS. You should be escaping the user's input before querying the database (or, ideally, use prepared statements ) or you may find yourself being hacked very quickly if released to the public.
