 Posted: Thu May 11, 2017 1:13 am Post subject: Mysql array pulling certain fields and values |
 |
|
Hello, I am new to smarty. I am trying to figure out how to pull data from array from a mysql php file. I do not want all the fields in the table just three. I am trying to only pull id name and category fields and values and loop through them in a table. I don't need to display all the fields. i know I can select the fields in my select statement, but I want to understand how to pull certain fields and values to display them only if my select has *.
| Code: |
$query = "SELECT * FROM Recipe;";
$result = mysqli_query($db_server,$query);
while($row = mysqli_fetch_assoc($result)){
$id=$row["id"];
$name = $row["name"];
$description =$row["description"];
$instructions = $row["instructions"];
$category =$row["category"];
$created_date = $row["created_date"];
$rows[] = $row; # $data is the array created for use in the Smarty template.
//Assign PHP variable to Smarty template
$tpl->assign('rows', $rows);
$tpl->assign('id', $id);
$tpl->assign('name', $name);
$tpl->assign('description', $description);
$tpl->assign('instructions', $instructions);
$tpl->assign('category', $catagory);
$tpl->assign('created_date', $created_date);
}
// Display template
$tpl->display('listrecipes.tpl');
?>
|
My smarty template listrecipes.tpl
| Code: |
<!-- page title -->
<h1>List of All Recipes</h1>
<table border="1" cellspacing="1" cellpadding="1">
<tbody>
{if $rows}
<tr>
<th scope="col">Recipes</th>
</tr>
{section name=row loop=$rows}
<tr>
{foreach from=$rows[row] key="Key" item="Value"}
<td><a href="recipe_detail.php?={$Value}">{$Value}</a></td>
{/foreach}
</tr>
{/section}
{else}
<h1>NO ROWS FOUND</h1>
{/if}
</tbody>
</table>
</div>
</body>
</html
|
I would appreciate any help with this and the proper code. I have it displaying all the fields. |

How is this a Smarty problem?

Then request only these fields, instead of all of them.
| Code: | <?php
$pdo = new PDO('mysql:...', $user, $pass, [
PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION,
PDO::ATTR_EMULATE_PREPARES => false,
PDO::ATTR_DEFAULT_FETCH_MODE => PDO::FETCH_ASSOC
]);
$query = $pdo->prepare("SELECT `id`, `name`, `description`, `instructions`, `category`, UNIX_TIMESTAMP(`created_date`) `date`
FROM Recipe;");
$query->execute();
$tpl->assign('rows', $query->fetchAll());
// Display template
$tpl->display('listrecipes.tpl');
?>
|
| Code: |
<!-- page title -->
<h1>Recipes</h1>
{foreach $rows as $row}
{if $row@first}
<table border="1" cellspacing="1" cellpadding="1">
<tbody>
<tr>
<th scope="col">Recipes</th>
</tr>
{/if}
<tr>
<td><a href="recipe_detail.php?={$row.id}">{$row.name}</a> ({$date|date_format:"%F %H:%M"})</td>
</tr>
{if $row@last}
</tbody>
</table>
{foreachelse}
<h2>No recipes found</h2>
{/foreach}
