SendGrid

4 hooks fired by SendGrid: 4 filters and 0 actions across 4 call sites. 4 of the 4 call sites are described by a docblock, at the call or on the constant that names the hook; the rest are listed with their signature and call sites only. Paths are relative to the plugin directory.

xpac-forms-after-settings-modal-content

Filter · 3 arguments · 1 call site

Content appended inside a settings panel's item modal.

applyFilters( 'xpac-forms-after-settings-modal-content', [], { value: options, onChange: onUpdate, }, `xpac-${ID}` )

Fired from:

• assets/packages/sendgrid/Components/Modal.js:85

xpac_sendgrid_attachment_budget

Filter · 1 argument · 1 call site

Filters the total size, in bytes, of the files one email may carry.

SendGrid refuses a message over 30MB with a 413, and base64 inflates every file by about a third, so the default leaves room for the template and the rest of the payload rather than aiming at the limit.

apply_filters( 'xpac_sendgrid_attachment_budget', 5 * MB_IN_BYTES )

• $budget (int) — Bytes of original file, summed across the message.

Fired from:

• packages/SendGrid/Addon.php:1015

xpac_sendgrid_email_field_value

Filter · 4 arguments · 1 call site

Filters a submitted field value before it becomes a SendGrid template variable.

Only the default branch of the field-type switch reaches this, so checklist, dropdown, radio, confirmation and file fields never pass through it: each of those builds its own display value earlier in the switch. The returned value is stored against the field's {{name}} variable, which is what fills the dynamic template data posted to SendGrid and the To / Reply-To substitutions on the action.

apply_filters( 'xpac_sendgrid_email_field_value', $data_value, $type, $key, $submission )

• $data_value (mixed) — The submitted value for this field, unmodified.
• $type (string) — Forms field type of the block the value came from, as resolved by Blocks::getFieldTypeByBlock().
• $key (string) — The field's name attribute, which is also the {{...}} variable the value is stored under.
• $submission (Submission) — The submission currently being processed.

Fired from:

• packages/SendGrid/Addon.php:819

xpac_sendgrid_request_timeout

Filter · 1 argument · 1 call site

Filters how long, in seconds, to wait for SendGrid to answer.

These requests no longer run inside the visitor's submission, so this is a tolerance for a slow API rather than a latency budget: nothing is waiting on it, and a timeout shorter than SendGrid's own response time turns a delivery that worked into a needless retry. Ten rather than WordPress's five, for that reason.

apply_filters( 'xpac_sendgrid_request_timeout', 10 )

• $timeout (int) — Seconds to wait. Default 10.

Fired from:

• packages/SendGrid/Client.php:75
