我试图运行我在php中创建的程序但在这种情况下我想使用codeigniter运行它。
我一直在努力获取表格而没有成功,这是我的旧代码:
<?php include('connect.php');
?>
<html>
<head>
<script src="http://code.jquery.com/jquery-2.1.1.min.js"></script>

</head>
<body>
<div class="container">
<div class="row">
<div class="col-md-12">
<a href="estudiante.php"><button type="button" class="btn btn-success">AGREGAR</button></a><br /><br />
<h2 align="center">TABLA:MATERIAS</h2>
<input id="busqueda_tabla" type="text">
<table class="table table-hover" align="center" border="1" cellspacing="0" cellpadding="0" width="700" id="tabla_busqueda">
<thead>
<th>id</th>
<th>Carrera</th>
<th>Nombre</th>
<th>Descripcion</th>
<th>Carga horaria (hs)</th>
<th>Accion</th>
</thead>
<?php
$sql=mysql_query("SELECT s.*, c.nombre AS carrera FROM materias s LEFT JOIN carreras c ON s.carrera_id=c.id");
$i=1;
while($row=mysql_fetch_array($sql)){
echo "<tr>
<td>".$i."</td>
<td>".$row['carrera']."</td>
<td>".$row['nombre']."</td>
<td>".$row['descripcion']."</td>
<td>".$row['carga_horaria']."</td>
<td align='center'>
<a href='editar.php?editar=1&iden=".$row['id']."'><button type='button' class='btn btn-primary'>EDITAR</button></a> |
<a href='borrar.php?borrar=1&iden=".$row['id']."'><button type='button' class='btn btn-danger'>BORRAR</button></a>
</td>
</tr>";
$i++;
}
?>
</table>
</div>
</div>
</div>
</body>
</html>
这是“连接”文件:
<?php
$con=mysql_connect('localhost','root','root')OR die('error : '.mysql_error());
$db=mysql_select_db('desafio');
if($db){
echo '';
}else{
echo 'Error :' .mysql_error();
}
?>
但我不知道如何使用Codeigniter进行操作,我无法从表“materias”和“carreras”中获取数据。我曾经想过这样的事情(这只是我的Crudmodel的一个例子):
<?php
Class Crudmodel extends CI_Model{
public function getRecords(){
$query = $this->db->get('materias');
if($query -> num_rows() > 0){
return $query->row();
}
}
}
?>
然后,这是我的控制器文件:
<?php
class Home extends CI_Controller{
public function index(){
$records = $this->Crudmodel->getRecords();
$this->load->view('home', ['records'=>$records]);
}
}
?>
最后,这是我的主文件(应该包含两个表的信息)
<?php include('header.php'); ?>
<?php include('footer.php'); ?>
<div class="container">
<div class="row">
<div class="col-md-12">
<h2 align="center">TABLA:MATERIAS</h2>
<input id="busqueda_tabla" type="text">
<table class="table table-hover" align="center" border="1" cellspacing="0" cellpadding="0" width="700" id="tabla_busqueda">
<thead>
<th>id</th>
<th>Carrera</th>
<th>Nombre</th>
<th>Descripcion</th>
<th>Carga horaria (hs)</th>
<th>Accion</th>
</thead>
<?php
$sql=mysql_query("SELECT s.*, c.nombre AS carrera FROM materias s LEFT JOIN carreras c ON s.carrera_id=c.id");
$i=1;
while($row=mysql_fetch_array($sql)){
echo "<tr>
<td>".$i."</td>
<td>".$row['carrera']."</td>
<td>".$row['nombre']."</td>
<td>".$row['descripcion']."</td>
<td>".$row['carga_horaria']."</td>
<td align='center'>
<a href='editar.php?editar=1&iden=".$row['id']."'><button type='button' class='btn btn-primary'>EDITAR</button></a> |
<a href='borrar.php?borrar=1&iden=".$row['id']."'><button type='button' class='btn btn-danger'>BORRAR</button></a>
</td>
</tr>";
$i++;
}
?>
</table>
</div>
</div>
</div>
希望你能帮助我:(

选择CI做得很好。
我们需要知道您遇到的错误,哪些文件和行,哪些部分不起作用,以及有关错误的更多详细信息。 但是,我可以提供一个清单进行故障排除。
这一页上将详细介绍最简单的步骤: http://www.codeigniter.com/user_guide/tutorial/news_section.html

<?php
Class Crudmodel extends CI_Model{
public function getRecords(){
$this->db->select('s.*, c.nombre AS carrera')
->from('materias s')
->join('carreras c', 's.carrera_id = c.id', 'left');
$q = $this->db->get();
if($q -> num_rows() > 0){
return $q->result();
}
return false;
}
}
?>
此?

以下更多编辑:
<?php
class Home extends CI_Controller{
public function index(){
$this->load->model('Crudmodel');
$data['records'] = $this->Crudmodel->getRecords();
$this->load->view('home', $data['records']);
}
}
?>
视图:
<table>
<?php
$i=1;
foreach($records as $record) {
// build your table view here
echo "<tr>
<td>".$i."</td>
<td>".$record->carrera."</td>
<td>".$record->nombre."</td>
<td>".$record->descripcion."</td>
<td>".$record->carga_horaria."</td>
<td align='center'>
<a href='editar.php?editar=1&iden=".$record->id."'><button type='button' class='btn btn-primary'>EDITAR</button></a> |
<a href='borrar.php?borrar=1&iden=".$record->id."'><button type='button' class='btn btn-danger'>BORRAR</button></a>
</td>
</tr>";
}
$i++;
