How To Retain Attributes Ina Class	View Content

I am making a project by designing my own MVC model. In this the user accesses controller class which further calls model class which accesses the database by $dbh attiribute defined public. My View is a script which calls different pages. In the constructor of model I'm establishing connection with the database. Firstly I construct the model object when the user accesses i.e. in the controller class to check in the databse then if the username is not present in the dtaabse I want to insert his info in the database for that I again calla model class but this time I again have to establish connection. Is the $dbh firstly constructed is lost like dangling pointers in C++. Do I have to worry about it. If yes how can I solve this problem.

Retain Listbox Value On Form Reload

Hi all,

I have a listbox on a form that gets it's data from a MySQL query, all of which is working fine.
I make a selection in my listbox and then submit the form which is reloading itself. However on the reload I would like the listbox to display the selection made by the user, instead it reverts to the first item in the list.
I have included the code, if someone could point me in the right direction that would be great.
I have searched these forums and tried a few things that are suggested but I still can't get it to work.

Code: [Select]
<?php
include("dbconn.php");

$query = "SELECT location.location_name, printer.model_number, location_printer.serial_number" .
" FROM location, printer, location_printer" .
" WHERE location.location_id = location_printer.location_id" .
" AND printer.printer_id = location_printer.printer_id";
$result = mysql_query($query);

echo "<table>";
echo "<th>Location</th>";
echo "<th>Printer</th>";
echo "<th>Serial No</th>";

while(($row = mysql_fetch_array($result)))
{
    echo "<tr>";
    echo "<td>".$row['location_name']."</td>";
    echo "<td>".$row['model_number']."</td>";
    echo "<td>".$row['serial_number']."</td>";

How To Retain Values In Simple Combo Upon Onchange Event

Similar Tutorials

Hi there,

I am having a PHP form with simple combo box. Here is the code:

<form name="form1" method="get" action="">
  <select name="select" onChange="form1.submit()">
    <option value='value1'>My Value1</option>
    <option value='value2'>My Value2</option>
    <option value='value3'>My Value3</option>
  </select>
</form>

Now the form is successfully being submitted upon 'onChange' event. The only thing I am trying to do is to retain the value of the new option. As every time I select the value from the combo, it goes back and displays the 'value 1' even when I select value 3 or 2.

How do I make the combo box retain the value as 3 (when I select option 3) after the form is submitted.

Please reply.

Thank you!

Retain Dynamically Added Rows On Click Of Back

Similar Tutorials

Hi,

I have set up 2 php pages

page 1 - add_entry2.php
In this page I have a invoice table created where I can dynamically add/delete rows. This has a View Bill button which takes me to page 2- add_entry3.php
In this page it shows up the rows added in page 1 in read only format, so if the user wants to modify the data that he/she entered then he must Click on <back> that i have provided in the page 2 which will direct him to page 1

Now the problem starts here
on click of Back the dynamically added rows dissappear..which is frustrating..I know its something to do with my code..but can anyone help me fix it.

One more thing is that i dont want to store the data into DB till the finalise button is clicked on page 2 so that means till page 2 is submitted nothing goes to DB from Page 1.

Newbie Question: In A De Form, How To Retain A Value In A Field And Display It As Disabled/greyed-out?

Similar Tutorials

Hello JS experts, I'm new to JS coding (self-learning) and I have just one (potenitally) simple request to ask of you wonderful folks here. Oh BTW, I've tried searching through this forum (and the WWW as well) but couldn't seem to easily find something that fits my request, or was easy for me to understand and apply to my situation. So what I have/want is: a Data-Entry form which (for the first record/entry for a given date) allows the user to select a date from a "Calendar Date Picker". Upon subsequent records/entries (for the same date), the date field should no longer be accessible, but the (previously entered/selected) value should be both displayed (greyed-out) and certainly carried over to the DB/Table. I know this might be a very simple piece of code, but being that I'm a newbie, I'm not sure how to achieve this. Would appreciate any and all help to get this done (preferably the necessary code). If it helps, here's some of my existing code that's related to the field names: Form field details:

                <div class="control-group">

                    <label class='control-label'>Select Flyer Start Date:</label>

                    <input type="text" name="datepicker" id="datepicker">

                </div>

DB (table) field details:

         $flyerDateStart = isset($_POST["datepicker"]) ? $_POST["datepicker"] : "";

Thanks much.

Replace Attributes By Tag Name

Similar Tutorials

I have a site that allows members to create pages. These pages consist of small sections some of which HTML can be entered. To keep visitors from straying away from the site, any outside urls are brought up in a modal window. Using inline attributes, a class has to be created (or added to), and the title tag requires some special characters. I can probably get around this by inserting an onclick or something, but there must be a way to replace attributes, and I am at a loss.
The text segments are stored in a database. What I want to do is change the <a> tag attributes as the page is created. So I have a segment of text "$TheText" and I want to change or replace the attribute values.
For instance,
If $TheText contains an 'a' tag that looks like this:
Code: [Select]
<a class="MyClass" title="Godzilla" href="http://www.godzillaslair.com">Godzilla</a>I would want to change it to
Code: [Select]
<a class="MyClass Lightview" title="Godzilla :: {Lightview's parameters}">Godzilla</a>Or even just replace the attributes entirely, so it would look like
Code: [Select]
<a class="Lightview" title="{Inserted Title} :: {Lightview's parameters}">Godzilla</a>
In other words, just replacing the attribute values.

Of course, I need to see if the attributes exist. I know how to do that and how to get their values. But all that tells me is that I have an 'a' tag in the text with those values for those attributes. I cannot, for example, then do a str_replace in the first example, because there may be another tag in the text with the "MyClass" class. I can iterate character by character between <a and </a> but there must be a better way.
I'm no good at regex, so I haven't even attempted that.

Any suggestions would certainly be appreciated.

Can Inheritance Be Used With Php 8 Attributes?

Similar Tutorials

Context.

Class AbstractTenantEntity's purpose is to restrict access to data to the tenant (i.e. account, owner, etc) that owns the data. Any entity which extends it will have the TenantId added when created and the TenantId in the WHERE clause for all other requests.

Tenant typically does not have collections of the various entities which extend AbstractTenantEntity, but does for a few of them do. When using annotation, I handled it by applying Doctrine's AssociationOverride annotation to the extended classes which should have a collection in Tenant.

use Doctrine\ORM\Mapping as ORM;

/**
 * @ORM\Entity()
 */
class Tenant
{
    /**
     * @ORM\OneToMany(targetEntity=Asset::class, mappedBy="tenant")
     */
    private $assets;

    // Other properties and typical getters and setters
}

use Doctrine\ORM\Mapping as ORM;

abstract class AbstractTenantEntity implements TenantInterface
{
    /**
     * inversedBy performed in child where required
     * @ORM\ManyToOne(targetEntity=Tenant::class)
     * @ORM\JoinColumn(nullable=false)
     */
    protected ?Tenant $tenant = null;

    // Typical getters and setters
}

use Doctrine\ORM\Mapping as ORM;

/**
 * @ORM\Entity()
 * @ORM\AssociationOverrides({
 *     @ORM\AssociationOverride(name="tenant", inversedBy="assets")
 * })
 */
class Asset extends PublicIdTenantEntity
{
    // Various properties and typical getters and setters
}

So, now I am changing from annotations to attributes, and modified AbstractTenantEntity as follows:

use Doctrine\ORM\Mapping\ManyToOne;
use Doctrine\ORM\Mapping\JoinColumn;

abstract class AbstractTenantEntity implements TenantInterface
{
    /**
     * inversedBy performed in child where required
     */
    #[ManyToOne(targetEntity: Tenant::class)]
    #[JoinColumn(nullable: false)]
    protected ?Tenant $tenant = null;

    // Typical getters and setters
}

Next I went to modify Asset and realized that there didn't appear to be an attribute for AssociationOverride. I found a little discussion on the topic on github but couldn't find any resolution.

Question

Can inheritance be used with PHP 8 attributes where the property is defined in the parent class and the attribute is applied in the child class? Googling php 8 attributes inheritance didn't provide anything and thus I expect the answer is no but thought I'd ask.

Thanks

EDIT. Maybe Doctrine does have an attribute version: https://github.com/doctrine/orm/blob/2.9.x/lib/Doctrine/ORM/Mapping/AttributeOverride.php

EDIT2. Actually don't think so

Code "back" Button To Retain Values From $_post

Similar Tutorials

Hi,

I have set up 2 php pages

page 1 - add_entry2.php
In this page I have a invoice table created where I can dynamically add/delete rows. This has a View Bill button which takes me to page 2- add_entry3.php
In this page it shows up the rows added in page 1 in read only format, so if the user wants to modify the data that he/she entered then he must Click on <back> that i have provided in the page 2 which will direct him to page 1

Now the problem starts here
on click of Back the dynamically added rows dissappear..which is frustrating..I know its something to do with my code..but can anyone help me fix it.

One more thing is that i dont want to store the data into DB till the finalise button is clicked on page 2 so that means till page 2 is submitted nothing goes to DB from Page 1.

I am able to retain values if I use the code Code: [Select]
<form action="add_entry2.php" name="eval_edit" method="post" format="html">
i,e if I submit back to the same page and retrieve values form $_POST

but If I use the code Code: [Select]
<input type="button" value="Back" onClick="history.go(-1);return true;">to get back to add_entry2.ph it looses all the values. Is there any other way to code the BACK link retaining my $_POST values(Do you think $_SESSION would work in this case?)

Grabbing Data From Xml With Attributes

Hi,

Im trying to grab some data from a XML generated by an external server.
I know how to grab from XML without attributes, but I cant seem to wrap my head around the structure of this file.
What would be easiest way to get the value of the "dbnr" field?

Part of the XML file:

Code: [Select]
<data>
<location>
<field name="id" format="Long">xxxxxx</field>
<field name="dbnr" format="Long">xxxxxx</field>
<field name="jobnr" format="Long">xxxxxx</field>
<field name="job_type" format="String" maxlen="50">xxxxxx</field>
<field name="job_category" format="String" maxlen="50">xxxxxx</field>

Xpath Elements And Attributes

Similar Tutorials

Hi all,

I'm sure I'm making this far more difficult than I need to...

I've got an xml document...

<library id="1">
<lname>Lib1</name>
<book id="1">
<title>book 1</title>
<author>Author 1</author>
</book>
<book id="2">
<title>book 2</title>
<author>Author 2</author>
</book>
</library>

I can access the nested elements using xpath like :

$result = $xml->xpath('//book');

foreach($result as $books) {
echo $books->title;
}

How would I do this for the attributes? If I specify I want the attributes in the xpath query I can't get at the elements...

I'm trying to turn this xml file into a simple relational database... A library table and a book table.

So I need the library id (attribute) and the name(nested element) for one insert query - and the book id, title, author and the library id for the other.

Anyone got any idea?

Cheers
